Embodiment 1 FIG. 1 is a diagram showing the structure of an image display device according to Embodiment 1 of the present invention. 1 1 is a luminous body that emits light, 12 is a parabolic mirror that reflects light from the luminous body 1 1 into a substantially parallel reflection, and 13 is a condenser lens that condenses light reflected from the parabolic mirror 12. The luminous body 11, the parabolic mirror 12 and the condenser lens 13 constitute an illumination light source system (transmission device, illumination light source section).

1 4 is a micromirror device (transmission device, reflective image data distribution unit, Digital Micromirror Device, DMD, registered trademark of Texas Instruments Incorporated (TI)) for reflective light spatial modulation elements, micromirror The device 14 uses the reflecting surface to modulate the intensity of the light collected by the condenser lens 13 in space, and then uses the reflection intensity to modulate the light as a light image signal for supplying image data. The present invention can be applied to an image display device including all light space modulation elements, but it will be described below using a micromirror device 14. 1 5 series of refracting optical lenses (refractive optics) with barrel-type distortion aberrations (compensating aberrations), 1 6 series of convex mirrors (reflecting parts) with spool-type distortion aberrations, 1 7 series of refractive optical lenses Projection optics (projection optics) consisting of a convex mirror 16 The projection optics system 17 projects the light after the intensity is adjusted spatially using a micro-mirror device 丨 4 onto the screen 18.

496999 V. Description of the invention (17) ----- The screen (display position) that displays the image after the light projected from the light-sensitive projection system 17. The previous number indicates the light path. In the first embodiment, the reflecting surface of the micro-mirror device 4 is arranged parallel to the photosensitive surface of the screen 18, and the depth of the image display device becomes minimal. In order to avoid the shadow of the projected light (eclipSe), the micro-mirror device 14 and the screen 18 are arranged so as not to overlap in the height direction. In addition, the projection optical system 17 is configured such that the image of the micro-mirror device 14 and the image of the screen 18 maintain a conjugate relationship under the condition that the above-mentioned configuration of the micro-mirror device 14 and the screen 18 are satisfied. ^ The operation is explained next. The light output from the luminous body 11 is reflected by the parabolic mirrors 2 and then enters the reflecting surface of the micro-mirror device η from the oblique direction through the condenser lens 13. The micro-mirror device 14 adjusts the intensity of the incident light spatially according to the image data. The intensity-modulated light is projected onto a screen 18 by a projection optical system 17 to display an image. The user of the image display device looks at the image from the left side of the screen 18 in FIG. 1. y Here, the micromirror device 14 will be described. The micro-mirror device 14 has a reflecting surface in which a small square mirror of 1 6 // m is arranged in a two-dimensional array at a pitch of 1 7 # m. The small mirror and the image format generally correspond one-to-one. For example, by using a voltage applied from a controller not shown in the figure to individually change the tilt of each small mirror, the direction of reflected light from each small mirror can be changed individually. That is, when the reflected light from a small mirror is projected onto the screen 18, the tilt of the small mirror is changed as if the light is reflected in the direction of the opening of the projection optical system 17. In addition, the reflected light from a small mirror is not projected onto

All that is needed to change the tilt of the small mirror, below vwc, the micro-mirror device 14 can adjust the intensity of light at high speed. Because the mirror device 14 is a reflective type The light space modulation element can reflect the light modulation intensity of the light f in a direction inclined with respect to its reflection surface, and then reflects it. For example, in the case of using liquid crystal on the f light space modulation element, the light must be approximately from the inside of the liquid. For vertical injection, considering that the thinning of the image display device is limited by the lighting source system arranged inside, the effectiveness of the micro-mirror device 4 becomes apparent. As shown in this embodiment, by using the micro Reflector device 14, the illumination light source system is arranged on the side of the micro-mirror device 丨 4. The light source system can be arranged between the light space modulation element and the convex mirror that bends the light path to the screen 丨 8. Effectively use the space in the height direction of the image display device, It can prevent the illumination light source system from protruding. Next, the projection optical system 17 will be described. The light after the intensity is adjusted by the micro-mirror device 14 is reflected to the projection optical system 17. As shown in FIG. 1, the optical axis of the refractive optical lens 5 is set to It is perpendicular to the reflecting surface of the micro-mirror device 14 and the photosensitive surface of the screen 18, and deviates from the center of the micro-mirror device 14 and the center of the screen 18. Therefore, only a part of the viewing angle of the refractive optical lens 15 is used from the micro-mirror device. The projection of the light of the mirror device 14. In FIG. 1, the light is emitted upward due to the light self-refractive optical lens 15 coming in.

When the private 2 micromirror that represents a grid-like image (Figure 2 (a)) is projected, the grid-like image becomes Wooden barrel type (graphical lens 15 type distortion aberrations have compensation that occurs in convex mirrors 1 and 6. 1) The characteristics (compensation aberrations) of the barrel (Figure 2 (c)) are based on? Designed according to the spool twist of the screw 106 which compensates the distorted light when projected onto the screen 18 (Fig. 2 (d)).-Generally, the image changes that also occur with signal processing but due to the image Deterioration of the fineness' In the present Example 1, the distortion aberration is optically compensated. Here, the bobbin-type distortion aberration of the convex mirror 16 will be described. Fig. 3 is a conceptual representation of the optical path tracking to obtain the difference through the aberration-free. Refractive optical lens 19 is a diagram of a method of reflecting an image when the light from the micro-mirror device 14 is reflected by the convex mirror 16 or the flat mirror 21. In FIG. 3, the light path reflected by the flat mirror 21 is shown by a solid line, and the light path reflected by the convex mirror 16 is shown by a broken line. A self-micromirror device u emits a grid-like image (Figure 3 (a)) In the case of light, the image of light transmitted through the aberration-free refractive optical lens 19 will not be deformed (Figure 3 (b)). Therefore, the plane mirror 21 is used to transmit the reflection through aberration-free refractive optical After the light from the lens 19, when viewed on the AA cross section perpendicular to the optical axis 20 of the refractive optical lens 19, it becomes a black dot (Lu) with equal intervals (Figure 3 (d)). In the case of a projection optical system composed of a refractive optical lens 19 and a flat mirror 21, a lattice-shaped image is kept straight without distortion aberration. However, a convex lens 16 reflects and transmits a refractive optical lens with no aberration.

After the shape of the convex mirror 16 is determined, the calculation result design diagram can be used to calculate the bobbin-type distortion aberration, as long as the distortion aberration of the aperture learning advance lens 15 can be calculated according to the distortion design method. Regarding this, here in the province * just explain the name according to the design of the conventional refractive optical system. The barrel = j = enables the use of a refractive optical lens 15 like the & service aberration of the bobbin-type twisted aberration band of the compensating convex mirror 16, which can enlarge the deformed shirt image on the screen 18,: 爻Constituting the composition screen 18 with respect to the respective components of the image display device, the convex mirror 16 has a shape that uses an aspheric surface that is rotated by a quadratic curve around the red silk as its reflection surface ::; Significantly reduce manufacturing costs. ^ Kogu Easy Manufacturing Co., Ltd. can design convex mirror 16 freely, as long as it is designed with barrel-type distortion of bobbin-type distortion aberration ^ mirror 16 is acceptable. 1 the difference of refraction before learning the lens 15 again, in the conventional technology, as shown in Figure 96, one of the shadow optics 17, but also need to bend the light path, except for the TT cast 1, because the projection optics 17 part It is also right. As soon as the number of elements in this embodiment is reduced, the silver magic first path can be shortened: the optical effect of the curved effect is shown in the large surface of the illumination light source system, and the reflection comes from the projection optics system. The flatness of the light — ^ ^ status, chasing to the screen 18, you can make the most of the space where the mirror 22 hunts and bends the light path. Besides

496999 V. Description of the Invention (21)-It is also possible to replace the plane mirror 22 and the projection optics 17 and make it possible to use a projection optical device different from the projection optics 17 instead of the plane mirror 22. As shown above, according to the first embodiment, because the transmission device is included, it is composed of an illumination light source system and a micro-mirror device 14 and outputs a light image signal whose intensity is adjusted according to the image data; the screen 8 receives the light image After the signal is displayed, the image according to the image data is displayed; the convex mirror 丨 6, which has negative power, reflects the light modulated by the image data to the screen 18; and the refractive optical lens 15 ′ has a wood-like distortion aberration compensation lens 16 The barrel-type distortion aberration is set to project the light from the transmission device onto a convex mirror; it can compensate the spool-type distortion aberration of the convex mirror 16 that accepts the light modulated according to the image data and displays the enlarged image on the screen. 8 The screen 8 can be arranged at the position most suitable for the thinning of the image display device, and the effect of forming a thinner image display device than in the past can be obtained. In addition, according to the first embodiment, the illumination light source system composed of the illuminant 11, the parabolic mirror 12 and the condenser lens 丨 3 is used, and the light incident from the illumination light source system is adjusted and reflected according to the image data.

The result is that the aspheric shape can be sharply cut, and the manufacturing cost can be easily reduced by using a mirror lathe. & Example 2 In Example 1, a refracted light having a barrel-type lens 15 and a convex lens having a bobbin-type distortion aberration was used to obtain 17 as a projection lens 9 and a lens 16 to form a projection. Optics 糸 Η In this example of the yoke, Insect Example 2 illustrates the case where the projection distance magnified image is the same as the convex mirror, and the projection optical system using the right lens is not used. Figure of Mirror Structure Fig. 5 is a structural diagram of an image display device according to Embodiment 2 of the present invention. In Fig. 5, 23 series of aberration-free refractive optical lenses (refractive optical section), 24 series reflect the light from the refractive optical lens 23 and project them to the screen 18 Fresnel mirror (reflecting section ^) 25 series of refractive optical lenses Projection optics (projection optics) composed of 23 and Fresnel mirror 24. Like the convex mirror 16, the reflecting surface of the Freuner mirror 24 has negative power. Here, the illustration of the illumination light source system is omitted. Fig. 6 is an enlarged view of a Freyn mirror. Fig. 6 also shows the convex mirror 16 shown in the first embodiment. As shown in the correspondence between the convex mirror 16 and the Freyna mirror 24 as shown in FIG. 6, the Freyna mirror 24 divides the reflecting surface of the convex mirror 16 into small sections, each having the same inclination as the part corresponding to the divided position, and Having the shape of a reflecting surface that becomes a periodic structure. It is understood from FIG. 6 that the shape of the Freuner mirror 24 is thinner than that of the convex mirror 16. FIG. 7 is a graph comparing the difference in distortion of the aberration of the convex mirror 16 and the Fresnel mirror 24. FIG. As described in Example 1, the convex mirror 16 reflects the light path (dashed line in FIG. 7c) of the grid-like image (FIG. 7a, b) of the micromirror device 14 or the aberration-free refractive optical lens 23 due to the convex surface.

Explanation of the invention (23) Difference in shooting position 'AA perpendicular to the optical axis 27 of the refractive optical lens 23, a linear distortion aberration on the wearing surface (Figure 7c, 0). However, in the case of using the lens 24, since the reflection positions in the optical axis direction are all the same, no distortion aberration occurs as in the plane mirror 21 of FIG. 3 (FIG. 7d, #). Therefore, by using the Fresnel lens 24 to form the projection optical system 25, it is not necessary to consider the compensation of distortion aberration 'and use the refractive optical lens 23 without aberration. The other structures and operations are the same as those of the first embodiment, and descriptions thereof are omitted.

As shown above, according to the second embodiment, the image of the light transmitted after magnifying the image at a short distance is not imparted to the deformed Fresnel lens 24 and the aberration-free refractive optical lens because of the use of a convex lens and a convex lens. 2 3 constitutes a projection optics system 2 5 ′ The image can be enlarged and displayed on the screen 8 without having to use a refractive optical lens to compensate the bobbin-type distortion of the convex lens of Example 1 and the design of the image display device can be obtained. The effect of making it easy. In addition, according to the second embodiment, the use of a Fresnel mirror 24 having a structure thinner than that of the convex mirror 16 in the projection optical system 25 results in an effect that an image display device that is thinner than that of the embodiment j can be obtained. Embodiment 3 In this embodiment 3, a description will be given of a configuration in which light is formed by a convex-shaped reflecting surface.

^ ^ ^ The situation where the optical element and the refractive optical lens on the opposite side constitute a refractive optical lens. FIG. 8 is a structural diagram showing an image display device according to a third embodiment of the present invention. In Figures 8 and 28, refracting optics fk disc μ, Euqian edge mirror (refracting optics), 29 series are composed of two kinds of optical materials with different dispersion characteristics.

FIG. 9 is an enlarged view of the optical element 29. 31 and 33 are low-dispersion glass (low-dispersion medium), high-dispersion glass (high-dispersion medium), 3 2 is the boundary surface of low-dispersion glass 31 and high-dispersion glass 33, and 34 is a high-dispersion glass Boundary reflective surface. When viewed from the incident side of the light, the "plane" constitutes a concave shape as if it has positive power, and the reflective surface 34 constitutes a convex shape as if it has negative power. As with the principle of 稜鏡, chromatic aberration occurs when light enters the optical element 29. The combination of the low-dispersion glass 31 and the high-dispersion glass 33 is used to eliminate chromatic aberration. Next, the operation will be described.

FIG. 10 is a diagram showing an optical path incident into the optical element. In Fig. 10, the left side of the boundary surface 32 corresponds to the low-dispersion glass 3 (refractive index ^), and the right side corresponds to the low-dispersion glass 3 3 (refractive index? 2). And η2 can be arbitrarily selected, but here n〆%. Further, a convex mirror having the same shape as that of the reflecting surface 34 was prepared, and the convex mirror was used as the reflecting surface 34, and the optical path of only the incident light is shown by a broken line. Compared with the car line and dashed line, it is known that compared with the light path using a simple convex mirror to bend, it uses the structure to transmit low-dispersion glass 3 in order, 鬲 dispersion glass 3 3 and then enters the convex-shaped reflective surface 3 Optical element of 4 2 of 9

The light path can be bent at a larger angle, and a wider-angle image can be projected onto the screen 1 800. If the optical element 29 is used, compared with the convex mirror of the first embodiment, the projection image can be wider-angle The proportion makes the convex shape of the reflecting surface 34 smaller. The bobbin-type distortion of the reflecting surface 34 can be reduced. Also, because by

Description of the invention (25) The light emitting position of the light from the low-dispersion glass 31 or the high-dispersion glass 33 can be within the optical element 29; = Controllable thickness of the distortion aberration. door.卩 Compensation on the reflecting surface 34 The principle of eliminating the chromatic aberration of the optical element 29 will be explained next. The optical ® 1 folded back by the reflecting surface 34 in one direction is shown. In the graph ", the red 1 = light dagger graph is shown by solid line and dotted line, respectively. The case where the refractive index changes due to the difference in wavelength is called;; = road test, the relative situation is called low score. I. Glass material has a long; β long time and short time, the refractive index becomes large. Therefore, as shown in Figure 11, the low refraction of the blue wavelength at the low dispersion breaking glass 31 is large, and before the long wavelength is shot, the short dispersion glass 33, Tian Tuo 4 ^ Refraction is not as big as blue. The difference between the degree of refraction caused by the color of the high and low glass 33 α and the low ’is the difference in the color difference between the low-dispersion glass and the diffuse glass 31 that occur in the power ratio. In addition, it is possible to compensate for the achromatic aberration it # at low power. Therefore, by using this combination, it is possible to form a case of two f lenses as long as the low-dispersion glass 31 and the high-dispersion glass are used. The combination of garbage 3 3 can be reversed. In addition, in FIG. 9, the low-dispersion glass 31 is shown in FIG. 12, and it is also placed on the light-incident side on the same day. The dispersion glass 36 is lowered to the dispersion glass 38, and then the structured optical element 35 is relatively high, and the reflection surface 39 can be freely selected during design. According to the embodiment 3 shown above, since the use is made of low-dispersion puncture ρ ^ laminated in the direction of light transmission, the application is composed of the light ^ ^% ^ government break glass 31 and the dispersion glass 33 7 has become a low-dispersion glass 31 and a high-dispersion glass with reflection and transmission. Page 28 2103-3823-PF; AHDDUB.ptd 496999 Description of the invention (26) 33 The light reflecting surface 34 of the optical element 29 projects the light onto the screen 18. It is possible to project a light with the same wide angle as the convex mirror of Example 1 in a more gentle convex shape, and the thickness of the low-dispersion glass 3 or the high-dispersion glass 3 3 can be adjusted inside the optical elements 29 and 35. The effect of compensating for the distortion aberration occurring on the reflecting surface 34 and obtaining the bobbin-type distortion aberration occurring on the reflecting surface 34 becomes easy. Example 4 Figure Figure. In the device, the spherical convex fold 43 is provided, and the reflective spherical transparent light source is refracted by the reflection. In the present example, 1 of the spherical convex position 14 is 3, which shows the structure of the image display device of the fourth embodiment of the present invention.

Throughout Example 4, the optical element with an aspherical surface that has the non-optical surface should be in line with the 77-month deficit, so that the distortion aberration can be compensated. As shown in FIG. 13 (a), the reflection through the batch mirror 41, the optical lens 40, and the non-facet mirror 4i are used to reflect the light from the air as a light, and then the light will be removed. After the micro-mirror of the decaying element of the cymbal is lighted, the light technology shadow is moved to the screen 18 (not shown).

Description of the invention (27) As shown in FIG. 13 (b), an aspherical lens 42 is provided at a scattered position of the main ray between the refractive optical lens 40 and the spherical convex mirror 43, and the refractive lens 40, The aspheric lens 42 reflects the light from the micro-mirror device 14 using a spherical convex mirror 43 and projects the light onto the screen 18. i Because the shape of the reflecting surface of the aspheric convex mirror 41 or the aspheric lens 42 of the aspheric lens 42 corresponds to the one-to-one correspondence, in either case, the shape is designed to reduce the distortion by using optical path tracing. Therefore, in any of the cases of Figs. 13 (a) and (b), it is necessary to use the aspheric convex mirror 41 and the aspherical lens 42 having a spherical shape as the medium to transfer the light from the shirt to the screen 1 8 ' The image display device is thin and can compensate the distortion of the image projected onto the screen 18. As shown in FIG. 13 (c), both of the aspherical lens 4 and the aspherical convex lens 41 may be included. By doing so, it is easier to compensate for distortion aberration. In addition, although the illustration is omitted, the aspherical lens 42 is not limited to one, and the refractive optical lens 40 and the aspherical convex lens 41 (or the spherical convex lens 4 3) are attached. It is also possible to include a plurality of aspheric lenses 42 in between, which can more compensate the distortion aberration. In order to make the compensation of distortion aberration using the aspheric shape described above more effective, there are three methods as follows.

Of course, it is also possible to manufacture and shape, and use plastic material temperature range and wet selection, as long as it is developed, used, and specified. Example 5 If the aspheric convex mirror on the implementation surface compensates the distorted image surface Bending, reducing the occurrence of image surface bending In the examination of the image (Petzval) and PP resin made of refractive optical lenses, productivity is reduced ~ the effect of the cost of the image display device. The aspheric lens 42 is formed by the "two-break glass molding method" in this case, which is made of glass material: compared with the case of material manufacturing, it can be mentioned]; the spherical lens degree range, etc.).

Description of the invention (32) For a planar object, the condition for obtaining a planar image without curvature of the image plane is called Petzva 1 condition. When p When = 0, Petzval conditions are satisfied. That is, in an image display device, by reducing Petzva 1 and approaching 〇, an image with reduced image surface curvature can be displayed on the screen 18 〇 # As shown in FIG. 17, consider a refractive optical lens (projection The optical device, the refractive optical section, the Petzval, and the compensation lens 48 are applied to, for example, the case of FIG. 13 (a). The refractive optical lens 48 is an achromatic lens composed of a positive lens 48a and a negative lens 4 8 B. Now, consider the aspheric convex mirror 41 (i = 3), because the refractive index n3 = ~ 1, and it has a negative power 03 (< 〇) with a large absolute value. By the division between negative values, the aspheric convex mirror 4 1 Petzva 1 and contribution station Petzval and contribution component P3 are easy to become positive. Therefore, by designing the refractive optical lens 48 which cancels the contribution component p 3 of the aspherical convex mirror 41, the curvature of the image plane is compensated. That is, a refractive optical lens 48 ′ composed of a positive lens 48A (i-2) having a positive power and a negative lens 48B (i-2) having a negative power is used to make the The component P1 + P2 becomes a negative value, so that the component p3 of the aspherical convex mirror 41 is canceled. First, since the positive lens 48A has a positive power 01 (> 0), by making the refractive index nl of the positive lens 48A larger, the contribution components P1 = 0 1 / nl and 0, so that the etzva 1) and the effect. As shown above, by changing the refractive index of the positive lens 48A and the negative lens 48B to nl > n2, making P1 + P2 as close to a negative value as possible can reduce the effect of ρ + ρ2 on p3.

2103-3823-PF; AHDDUB.ptd page 35 496999 V. Description of the invention (33) In addition, by setting the Abbe number v 1 of the positive lens 48A and the Ab number u 2 of the negative lens 48B to close values, This can make Petzval conditions more satisfied. Generally, when the refractive index change caused by the wavelength change is Δη, it is defined by the Abbe number u = (η — 1) / △ η (η is the refractive index). When the Abbe number is small, it means that the dispersion value is large. Optical materials. When the combined power of the positive lens 48A and the negative lens 48B of the refractive optical lens 48 of FIG. 17 is Φ, the formula of the combined power is φ = Σ (0〇 and the formula of achromatic conditions Σ (0 i / z; i ) = 〇 to get the formulas (2) and (3). Φ 1 = Φ · ^ 1 (v \ — v 2) (2) 02 = — φ · vv \ — v 2) (3) Put the formula ( 2) and (3) are respectively transformed into expressions (4) and (5), and the changes of the absolute values of (0 1 / φ) and ($ 2 / Φ) of (^ 2/1) are shown in the figure 1 8 shown. 0 1 / Φ 二 1 / [1 — (v 2 / w1)] (4) Φ ^ / V2 / v \) / [\ v2 / v \)] (5) In Figure 18, the horizontal axis represents (V 2 / Μ), and the vertical axis represents the absolute values of the expressions (4) and (5) | 0ΐ / φ || 02 / ΦΙ. It is known from FIG. 18 that the closer (1) is to the value 1, that is, the closer the value of v1, the greater the power, 02 of the positive lens 48A and the negative lens 48B. Using the result of FIG. 18, the power of the positive lens 48A and the negative lens 48B constituting the refractive optical lens 48 is increased, so that the Petzval condition can be more satisfied. That is, the refractive index of the positive lens 48A is "larger, and the refractive index of the negative lens 48B" is made smaller. The Abbe number of the positive lens 48a ^ 丄 and the Abbe number of the negative lens 48B ^ 2 are set to close values .

For example, let the refractive index of the positive lens 48A and the negative lens 48B be "two π 2 = 1.6, and let the Abbe numbers of the positive lens 48A and the negative lens 48B be ^ Bu 50, ^ 2 30, respectively. (2), (3) Assuming the combined power φ = 1, then 0 1 = 50 / (50-30) = 2.5, 02 = — 30 / (50-30) = ~ h5, at this time the refractive optical lens Petzval of 48 and becomes pi + p2 = (2 5/1 6) + (— 1.5 / 5/1 6) = 0. 625. * * If this is the case, it is close to the effect cut (P etzva 1) Normally, the refractive index of the positive lens 4 8 a becomes larger, and the refractive index of the negative lens · becomes smaller. For example, = 8 and η2 = 1.6. Make the refractive index of the positive lens 4 8A larger than the negative lens. At the refractive index of 48B, the Petzval sum becomes P1 + P2 = (2.5 / 1.8) + (~ 1 5/1 6) = 0.44514, which is closer to a negative value than before changing the refractive indices nl and n2. Improve Petzval (P et ζ ν a 1) and. Then, set the Abbe numbers of the positive lens 48A and the negative lens 48B, and > 2 to close values. For example, 1 = 4 5, 2 = 4 In general, make the difference ul of the Abbe number small — and get 01 2 45 / (45-43) = 22.5, 42 = —43 / (45—43) = — 21 from equations (2) and (3). 5 ( Let φ = 1), Petzval and P1 + P2 = (22 · 5/1 · 8) + (-21 · 5/1 · 6) =-0 · 9 'can make the refractive optical lens 48 Petzval and P1 + P2 become negative values. Therefore, the values of Petzval and P of FIG. 17 including the aspherical convex mirror 41 can be made close to 0, and the curvature of the image plane can be reduced. As shown above, according to the fifth embodiment, since the refractive optical lens 48 is included, it is composed of a positive lens "A having a positive power and a negative lens 48B having a negative power, so that the refractive index of the positive lens 48A is greater than that of the negative lens 48B. The refractive index of the positive lens 48A and the negative lens 48B Abbe number

V. Description of the invention (35) A value close to that compensates for distortion aberration, and satisfies the Petzval (p) condition, which can compensate the curvature of the image plane and obtain the effect of improving imaging performance. In addition, in the above description, the refracted light: lens 48 of FIG. 17 is used in FIG. 13 (a), but this embodiment 5 is not limited to this, and can also be applied to other structures shown in Example 4 . (Embodiment 6) In this embodiment 6, a method for generating an excessively large image surface curvature using a refractive optical lens in order to compensate the image surface curvature occurring in an aspherical convex mirror will be described. Fig. 19 is a diagram illustrating an excessively small image plane curvature occurring in an aspherical convex mirror. In Fig. 19 (a), the 49 series refracting optical lens, the 50 series refracting optical lens 1 and the optical axis 51, 51 are planes perpendicular to the optical axis 50. The light transmitted through the refractive optical image is imaged on the plane 51, and a flat image is obtained in FIG. 19 (a). Convex surface 3 This optical lens 49 projects light to Example 1 [Spherical surface, spheroidal lens] The aspherical convex lens has a small image surface curvature, which means that the good image surface becomes a curved surface with a concave surface facing the projection optical system side. For example, as shown in FIG. 19 (b), when the self-refracting optical lens 49 emits light toward ^, the reflected light is displayed as the image plane 52, and the screen 18 displays a blurred image. In order to compensate = 4: the image plane is too small to bend in the refractive optical system ::: to bend, so that the projection image plane is flattened. The human image plane, as shown in FIG. 20, is produced by using a refractive optical lens (optical device, a spherical projection light convex portion, and an image surface curvature compensation lens) included between the micro-mirror device: the mirror 41. The image surface 53 with a curved image surface 53 whose distance from the optical axis 44 to a distance away from the ^ point becomes too large, refracts optics

2103-3823-PF; AHDDUB.ptd Page 38 496999 V. Description of the invention (36) The image surface of the lens 54 is too large and the aspherical convex lens 41 is the image surface of the one that is too small • The curvature is offset. By doing so, it is possible to compensate an excessively small image plane curvature of the aspherical convex mirror 41 used for compensating the distortion aberration, and it is possible to display an image having no distortion aberration and no image curvature. The shape of the refractive surface of the refractive optical lens 54 can be determined by the numerical calculation of the optical path trace using a computer to determine the optimal shape of the refractive surface. Also, by applying aspherical optical elements to the scattered places of the principal rays or the concentrated places of the principal rays, it is known from the numerical calculation results of the optical path tracing that the distorted aberrations of the principal rays can be effectively reduced, and Concentration of light can effectively reduce the curvature of the image plane. One example is shown in Figure 2 丨. FIG. 21 is a diagram in which aspheric surfaces are applied to a place where light is concentrated or a place where light is scattered, so that aspherical lenses (projection optics, refractive optics, etc.) And aspheric lens elements 55), aspherical lenses (projection optics, refractive optics, aspherical optics) 56A, 56B are provided at the scattered points of light from the aspherical lens 55, An aspheric convex mirror (projection optics, reflecting part, aspherical light: π pieces) 57 is provided at the scattered position of the light of 566, and the light reflected by the aspherical convex mirror 57 is projected onto the screen 18 on the screen. The aspheric lens 55 can effectively reduce the curvature of the image surface. The aspheric lens, the mirror 56 A 5 6B, and the aspherical convex lens 57 can effectively reduce the distortion image. However, the z-series distance <numerical example 6A> 22 shows one of the aspherical surface definitions of the numerical calculation results of Fig. 21 as shown in equations (6) and (7)

Description of the invention (37) According to the sagging amount of the rotation center of the optical surface, c is the curvature (reciprocal of the radius of curvature) of the surface apex, k is the cone coefficient, and r is the distance from the z axis. In addition, the element systems of FIG. 22 are f = 5.57 mm (focal length at a wavelength of 546.1 nm), NA = 0 · 17 (numerical aperture on the micromirror device side), and Υ 〇b = 1 4 · 2 2 mm (micromirror Device-side object height), M = 86 · 3 (projection magnification). z-cr2 / [l + {l-(1 + k) c2r2} 0.5] + Ar4 + Br6 + Cr8 + Dr10 + Er12 + Fr14 + Gr16 Ten Hr18 + Jr20 (6) z = cr2 / [l + (l- (1 + k) c2r2} 0 * 5] + ARlr + AR2r2 + AR3r3 +… + If the image surface produced by the lens 54 is too large and the surface is applied to reduce distortion, other aspheric embodiments 7

If according to the sixth embodiment, the use of a refractive optical surface: curved 5'-convex convex lens 41 to compensate for the excessively small curvature of the image surface cancels it ::::: Compensated distortion aberration can be displayed and the effect of the compensated scene image can be displayed . If only according to the sixth embodiment, the dispersion of the light and the central / spherical shape of the main rays of light can effectively reduce the effects of image surface curvature and the aberration of the main rays in n. The refraction optical lens 54 that is effective at the previous dispersion can also be used.

The refracting optical lens 58 Placed in the image display light head: 32 * 4 * t 'mirror device 1 4 transmits the refractive optical lens 5 8/6. The reflected light is reflected to the convex mirror 60 side by the stopper mirror, the convex mirror reflects, and etched ~ a The stem light uses the plane mirror 2 2 reflecting surface and the screen 18 wide-angle projection described in Example 1. Among them, the configuration of the flat surface 22 of the plane mirror 22 is arranged in a light-sensing surface (or image display surface) in parallel, which can be used: t image display device. In this embodiment 7, the focus is on the empty space of the display device =: brother The 0 reflection comes from the light arranged in the image display 1+ soil group and the optical lens 58. Due to the configuration in the empty space, &gt; the sub-lens 58 or an illumination light source system not shown in the figure, the image display can be eliminated. Page 2103-3823-PF; AHDDUB.ptd 496999 V. Description of the invention (39) shows the thickness of the device. By comparing the effects of Figure 23 and Figures 24 and 59. Figure 25 can be understood that this optical path bending mirror, that is, Figure 24 Since the light path curve 60 is not included, it directly emits the light that transmitted through the refracting optical lens, brother 59, and to the convex mirror, the plane plane, and the mirror two. It is necessary to set the light path-curve mirror 59 on the screen 18 light-eran, because Bend the first axis of the refractive first lens 58 to the horizontal plane including the optical axis of the convex surface (詈 1: 5 is a vertical plane), and change the arrangement of the illumination light source system (not shown in the figure below m) on the 58th surface of the refractive optical lens. Higher than convex, the height of the lower part of the screen is higher than that of the image display device in Fig. 23 As shown in Fig. 2 and Fig. 3, the light path bending reflector 59 which reflects the light from the 8-folded convex lens 60 to the convex mirror 60 is used to reduce the thickness of the shirt image. , Can form a low height of the lower part of the screen. Although similar to the illustration is omitted, it is also possible to use an optical path bending mirror for a fold optical lens (a shadow optical device, a refractive optical section) composed of a plurality of lenses. An optical path bending mirror is inserted between one of the plural lenses of the refractive optical lens and the second lens device, so that the reflection of the optical path f curved mirror makes the light between the two lenses of the medium. The first device and the second lens device are composed of at least one refractive optical lens =: mirror. In this case, since the optical axis of the first lens device and the optical axis of the first lens device do not need to be coaxial, the two optical axes can be bent to form the refractive clothing 2103-3823-PF; AHDDUB.ptd page 42 496999 V. Description of the invention (40) Learn lenses. In this way, In addition, according to the number of lenses, the design of the light position of the lens intended to bend the optical path of the mirror is also designed. As shown above, the curved mirror 59, the optical lens 58 of the lens 58 is located in the image display, and the lower part of the screen is high. If the bending mirror is formed based on reflection, the axis can be bent. Folding can make a thinner effect. In the same manner as in Fig. 23, the case where the thin-type optical lens of the image display device is composed of a plurality of lenses makes it possible to use a complex optical path bending mirror. It is also possible to reflect the light from the refracting optical lens to the convex mirror and to reflect any light path bending reflector from the refracting optical lens to other lenses. It can be installed according to the image display. This embodiment is the first transmission optics and according to the seventh embodiment, because the refracted light is reflected at a proper angle in the horizontal plane including the optical axis of the optical path curved mirror 60, the refracted optical lens 5 can be refracted to the convex mirror. 8 or the empty space of the illuminating light source, to obtain the effect that a thinner and thinner image display device can be formed. Example 7 'Because the light path of the light path of the first lens device including the lens of the second lens device is bent and the optical axis of the second lens device and the light lens of the second lens device are used, the lens is arranged in an empty space to obtain an image display with a low height below the screen In addition to the device, Embodiment 8 This embodiment 7 can be applied to each of the embodiments 16 as the numerical embodiment 6 of the embodiment 6 A — # — j /.

Fig. 26 is a diagram showing the structure of an image display device according to the eighth embodiment of the present invention, using numerical embodiment 6A (Fig. 21). The same symbols as in FIG. 4 are micromirror devices. In Fig. 26, 62 are reverse optical systems (projection optics, refractive optics) consisting of a positive lens group with a positive power and a negative lens group with a negative power, and 63 are refracting optical lenses (the optical angles for fine adjustment of the light output angle) Projection optics, refractive optics), 64 series aspherical convex mirrors (projection optics, reflecting parts) that reflect light from a refractive optical lens and compensate for distortion. The illustration of the lighting source and the screen is omitted. The light from the micro-mirror device not shown in the figure is transmitted through the reverse optical system 62, and then exits through the refractive optical lens 63 to the convex mirror 64, and is projected onto a screen not shown in the figure. At this time, the reverse optical system 62 has a light-condensing effect and assists in expanding the image angle of the light projected onto the screen. Further, the refractive optical lens 63 has a function of distorting the distortion aberration that the aspherical convex mirror 64 cannot completely compensate. The reverse optical system 62 or the refractive optical lens 63 includes various refractive optical lenses described in the embodiments. More specifically, two groups of positive lens groups 62 A, 62B and one group of negative lens groups 62C in FIG. 27 (a), and two groups of positive lens groups 62D, β2E, and j group 62F in FIG. 27 (b). (Figure) (cOii group positive lens group 62 (^ and one group of negative lens group 62H each constitute a reverse optical system 62. The above structure is a structure derived by numerical calculations to achieve the purpose of the present invention.) The numerical calculation results shown in each numerical example can be easily understood by performing numerical calculations, and the distortion aberration or image plane f can be suppressed.

The difference between the Abbe number and the average value of the refractive index of the glass material is dif ave_ Features 1 and 2 correspond to the high refractive index of the folded positive lens 48A shown in Example 5, which makes the refractive index of the negative lens 48B low and low. Generally, an Abbe number of 70 to 90 is also used for applications such as achromaticity. However, it is known from feature 2 that the value of the Abbe number is 60 or less. The above are the results of numerical examples derived using numerical calculations of optical path tracking using a computer. In the present invention, 'because the micro-mirror device is eccentrically arranged outside the common optical axis of the projection optical system', the light enters the optical system obliquely. Care must be taken to prevent a part of the light from being blocked by a lens frame or the like, thereby reducing the effective beam. In the eighth embodiment, in order to eliminate the shadow of light, it is configured as shown in FIG. That is, in the structure of FIG. 26, the back focal length (Back Focal Length, BFL for short) is made after the distance from the lens closest to the micromirror device 14 to the micromirror device 14 (the light exit surface of the transmission device). Consistent with the distance from the micro-mirror device 14 to the entrance pupil position of the reverse optical system 62, minimizing the shadow of light can improve the lighting efficiency of the screen. The reason is explained below. The principal rays reflected by the small mirrors of the micro-mirror device 14 are concentrated at the entrance pupil position. Because the diffusion angle of the reflected light from each small mirror is fixed, as shown in Figure 4 0 (a), at the entrance pupil position and B F L-

In addition, the Abbe number of 70 ~ 90 is also used for achromatic and other purposes, but according to feature 2, it is known that the value of Abbe number is 6 〇 Below. The above are the results of numerical examples calculated using numerical values of optical path tracking using a computer. In the present invention, since the micro-mirror device is eccentrically arranged outside the common optical axis of the projection optical system, light enters the optical system obliquely. Pay attention to avoid the light; The part is blocked by the lens frame, etc., so that the effective light beam is reduced. In this embodiment 8 'in order to eliminate the shadow of light, it is structured as shown in Figure 26. That is, the structure in Figure 26 makes From the closest to the micromirror device 14 Back Focal Length (BFL) after the distance to the micro-mirror device 14 (the light exit surface of the transmission device) and the distance from the micro-mirror device 14 to the entrance position of the reverse optical system 62 Consistently 'Minimizing the shadow of light can improve the lighting efficiency of the screen. The reason is explained below. The main rays reflected by the small mirrors of the micromirror device 14 are concentrated at the entrance pupil position. The diffused angle of the reflected light is fixed, as shown in Fig. 4 (a).

2103-3823-PF; AHDDUB.ptd Page 47 496999 V. Description of the invention (45) ---- The light at the BFL position is most concentrated, and the size (diameter) of the refractive optical lens 66 can be minimized. At this time, the refractive optical lens 65 that directs light from an illumination light source (not shown) to the medium of the micro-mirror device 14 does not block the light of the micro-mirror device 14 toward the refractive optical lens 66. However, for example, as shown in FIG. 40 (b), the size or configuration of the aspheric lenses 55, 56, and the micro-mirror device 14 remains unchanged, and when the position of the entrance pupil is shifted from the BFL, the master from each small mirror The light is concentrated at the shifted entrance pupil position, and the diffusion angle of the light is fixed. Compared with FIG. 40 (a), the light at the BFL position is diffused, and the diameter of the lens receiving the light becomes larger. Further, the light incident from the micro-reflection device into the refractive optical lens 66 is blocked by the refractive optical lens 65. This leads to a decrease in the effective light beam and deteriorates the lighting efficiency. For the above reasons, the distance from the micro-mirror device 14 to the entrance pupil position is equal to the BFL, whereby the size (diameter) of the refractive optical lens can be minimized, the shadow of light can be reduced, and the illumination can be improved. effectiveness. Of course, the method of minimizing shadows shown here can also be applied to other embodiments. In addition, as for the numerical examples 4a and 4B, the positions of the entrance pupil and B F L are almost the same. However, the best effect can be obtained by completely matching them. As shown above, if this embodiment 8 is used, the reverse optical system 62 consisting of a positive lens group and a negative lens group, a fine-tuning light emission angle = a refractive optical lens 63, and an aspheric surface that compensates for distortion aberration are included. The convex mirrors 64, 1 can provide effects of suppressing distortion aberrations or reducing the curvature of the image surface. According to the eighth embodiment, the positive lens group 6 2 A (6 2 D)

2103-3823-PF; AHDDUB.ptd Page 48 496999 V.

In addition, according to the eighth embodiment, since the reverse optical system 62 is constituted by the positive lens group 6 2 G and the lens group 6 2H, a more specific structure, distortion aberration, or curvature of the image plane can be obtained. Effect of image display device. In addition, if the refractive index of the negative lens is in the range of 1.45 or more and 722 or less according to the present embodiment 8, the refractive index of the positive lens is larger than &quot; 22 and smaller than 1,9. , To obtain the effect of a more specific ρ ugly aberration or an image display device with a curved and thin image plane. 4 and <Material No. 2 Buller ΐ According to this embodiment 8, because the average value of the glass material constituting the negative lens is set to 25 or more and 38 or less, and the average value of the shell material constituting the positive lens is set to be greater than 38 and less than 6 〇, to obtain an image display that can be distorted aberrations or image planes that are curved and thinned: According to the present Example 8 'because the average value of the refractive index and the composition ratio of the glass material constituting the positive lens The difference between the averages is 0. (4) The optical glass lens with negative penetration is obtained by i, to obtain the effect of a more specific image display device that can suppress the difference of formation and reduce the thickness. Aberration or curvature of the image surface In addition, according to the present embodiment 8, the difference between the average value of the Abbe number of the glass material and the average value of the glass number constituting the positive lens is greater than G. 16 ' Beibu's slope glass material constitutes refracted light 2103-3823-PF; AHDDUB.ptd page 49 5. Description of the invention (47) The lens is obtained, and the effect of a more specific and thin image display device can be obtained. The aberrations of the aberrations and the curvature of the image are described in accordance with Example 8 'because the BFL from the lens to the micro-mirror device 14 and the self-supporting mirror device 14 $ π ^ The distance from 1 ～ 4 to the position of the entrance pupil of the reverse learning 糸 62 is 1 /, which can minimize the size (diameter) of the refractive optical lens, and minimize the shadow of light and improve the lighting efficiency. Embodiment 9 In this embodiment 9, it is described that a negative lens having a negative power is arranged at a low position of a marginal ray from the micromirror device to the reflector, so that a petzval condition is satisfied. Method. Fig. 41 shows the structure of an image display device according to a ninth embodiment of the present invention. Figs. 41 (a) and (b) are an overall view and an enlarged view, respectively. Illustrations of the illumination light source section, the micro-mirror device, and the screen are omitted. In Figs. 41, 67, and 68, respectively, are refractive optical lenses, 6 and 9 are convex lenses having a positive Petz va and contributing components, and 70 are optical axes common to the refractive lenses 67, 68 and convex mirror 69. 71 is a side ray of light traveling from a micro-mirror device not shown in the figure toward the convex mirror 69, and 72 is a negative lens having a negative power arranged at a low position of the side ray 71. As described in Example 5, since the convex mirror 69 has a positive Petzval and a contribution component 'Petzval and the entire projection optical system composed of the refractive optical lenses 67 and 68 and the convex mirror 69 It is easy to become a positive value, and image surface bending occurs. Therefore, by adding a negative lens 72 having a large absolute value and having a negative power, a negative Petzval and a contribution component are generated.

2103-3823-PF; AHDDUB.ptd Page 50 496999 V. Description of the invention (48) The Petzval sum of the optical system becomes 0, which can reduce the side light when the lens 7 2 is disposed. The selection of the negative position of 71 as the position of the negative lens 72 is the focus of this embodiment 9. That is, in the ninth embodiment, f is between a micro-mirror device (not shown) and a convex mirror 69, so that a negative lens 72 is arranged at a low position of the side light 71. The light is concentrated around the optical axis 70 at a low position of the side light 71.

By doing so, since a small part of the light concentrated on the periphery of the center of the negative lens 72 is transmitted, the lens effect of the negative lens 72 on the light can be almost ignored. Therefore, for the optical path design based on the refractive optical lenses 67, 68, and the convex mirror 69, it is not necessary to consider the influence of the negative lens 72, and the positive Petzval and contribution components of the projection optical system can be offset. It is not necessary to consider the influence on the optical path, because only the absolute value of negative power and the refractive index of the glass material are considered so that the Petzval condition can be satisfied, and the image surface curvature can be easily reduced. More specifically, The reverse optical system 8 of 8 2 may be provided with a negative lens 72, and the reflective surface of the micromirror (the exit surface in the case of a transmissive optical space s-periodic element such as liquid 2) is equivalent to the side light The low level of 71 makes it possible to use a field flattner as the negative lens 72 and close to the reflecting surface (emission surface). The structure of the negative lens 72 is not particularly limited to one lens, so that a negative lens 72 composed of a plurality of lenses may be included. As shown above ', if the negative lens 72 having a negative power is arranged at the low position of the side light 71 according to the ninth embodiment, the negative lens 72 need not be considered.

496999 V. Description of the invention (49) For the lens effect of transmitted light, the Petzval and Petzval and Gong points that offset the positive of the projection optical system and the negative of the contributing component can be easily shot. Petzval conditions, to obtain the effect of an image display device that can form a small image plane. Example 10 In Example 7, in order to reduce both the thickness of the image display device and the lower surface of the screen, the refracting optical lens 58 and the convex entrance light path f-curve mirror 59 are included so that the j f optical path is included. In the tenth embodiment, it will be described that the curved mirror 59 and the refracting optical lens 58 are used to bend the optical path of the optical path in the surface of the water. The relative configuration bar of the convex mirror 60 is shown in Fig. 42. Fig. 42 is a diagram for explaining the bending of the optical path 40 (a) and (b), respectively, which are a side view and a top view-a set condition, and a front view of the figure. It is the same as FIG. 23 or two ^ = 40 (c) series convex mirrors 60. In FIG. 42, the m-type refractive optical lens 58: ^ is made with the same symbol “bending mirror 59” and the convex surface J is a refractive optical lens 58 assuming that the case is removed. The optical axis 73 intersects with the optical axis 61 at the horizontal plane at the water angle Θ. The optical axis 73 is shown in Figure 40 (b). P After the rotation is only 180 ~ 0, the morphing optical lens 58 intersects Line 1 has two parts: the horizontal plane of the package and the p of the optical path of the refracting mirror 59 to the convex mirror 60. The image close to the curved mirror 22 of the optical path shows that the seismic surface is two, the closest is flat, and the convex surface is set. . ;;;:; = \ Set___ Straight convex mirror setting 496999 V. Description of the invention (50) ----- — The position from the surface to the optical path bending mirror 59 (the distance between the optical axis 61 and "stop is b, Including the horizontal plane of the optical axis 61 and the intersection of the optical axis 73) is the point on the line of intersection that is closest to the convex mirror setting surface acoustic curve mirror 5 9 The point furthest from the convex mirror setting surface is called the farthest point For the closest point, the distance from the mirror setting surface is a, and the distance from the furthest point to the convex from the nearest point to the convex surface is c. The distance c becomes the longest distance from the convex mirror installation mirror to the m-plane 59. Optical path curved mirror In addition, the most ancient height from the optical path curved mirror 5 9 is set to „!, From the point Q to the convex mirror setting surface: from the distance = axis 61 to the projection position of the optical lens 58z to the convex mirror. Is g, self-folding to f. The distance g becomes the longest distance from the convex mirror setting surface to the refracting surface. Therefore, the position of the self-refracting optical lens 2 == to the horizontal direction to the convex mirror setting surface; 9 of f The sum of the sacrifice carving has also been learned from FIG. 42 (a). To minimize the height of the lower part of the screen, which is the distance from the bottom of the screen 18, the reflected light 75 to the convex mirror 60 of the silver axis 61 passes through. It is advantageous to make it as close to the optical axis as possible. However, when the optical path passes through a position that is too low, the optical path ^ counter == lives and becomes a shadow on the screen, which cannot be displayed = To ΐίΓ8 ::, you must avoid the optical path-curved reflection The mirror 59 covers the reflecting light of the convex mirror 60, which determines the size and position of the road bending mirror 59. Grid bow About the position of the light path bending mirror 59, in order to make the convex mirror reverse

2103-3823-PF: AHDDUB.ptd V. Description of the invention (51) The light is transmitted through the light path as low as possible. The thickness of the image display device is as large as possible because of $. And, about

The value of the distance C is 1 A / ^ (thickness determined by the specifications) TP 6. It is below the thickness limit value. According to the above conditions, the light rays including the refracting optical lens 58 are bent, and when the distance f is too short, the light rays up to the convex surface. The point P from which the curved reflection reaches P does not cover the light path f from the curved mirror 59 to the convex J-ray optical lens 58. The distance a becomes shorter than necessary. However, when the light reaches a distance, the position of the light-sensitive surface or the light path bending mirror 59 of 60 is: 'piece by ::: mirror == excessively far away from the light path and curved reflection; if the mirror 59 becomes large, the light path must be The curved mirror 5 = ::, then shields the reflection from the convex mirror 60 and then the angle is 75 again. Therefore, when there is the most V value at the distance _ there is a reflection angle at the lower end of the bending angle 1 and the bending angle Θ, as can be seen from FIG. 42. a becomes shorter, the height of the line 60 from the convex mirror toward the lower end of the screen 18 is increased. Conversely, if the bending angle Θ is made smaller, the distance g or distance c is also reduced. The refractive optical lens 58 or the optical path bending mirror 59 is advantageous from the viewpoint of thickness. However, when the bending angle 0 is too small, a part including the point P of the refractive optical lens 58 enters the light path from the light path bending mirror 59 to the convex mirror ⑽ as a light path to block light, and a part where a shadow cannot be projected occurs. Therefore, there is also an optimal value at the bending angle 0. According to the above matters, from the optical path bending mirror 59 to the convex mirror 60

2103-3823-PF; AHDDUB.ptd Page 54 V. Description of the invention (52) For the light path of Shizhi, if the point p is set in a range that does not block the light, the bending angle Θ of the light path is fixed. It is determined that the approach is close to the first line and the bending angle is 0—therefore, the time limit image is again the distance g or distance C, which is the larger of these distances: the limit value generally determines the distance f. In particular, the distance, ", and the degree of drought can suppress the height of the lower part of the screen to the minimum. When equal, # & In addition, there are other 彳 if #% I i α according to the image display device, but the same as the above, The above results are sorted into the following 1 ~ 3 0M signs, and the distance f and the bending angle Θ will be optimized. °: The shaded parts like the following are obtained, which can meet the thickness limit of 3 values \ = ^ height suppression The lower part of the screen is restricted. 1. The light path from the light path bending mirror 59 to the convex mirror 60 is not blocked when the light path is bent by the light path bending mirror 59. The P point of the refractive optical lens 58 is as close as possible. This optical path determines the angle of the two circumferences. In the case of Θ according to other conditions of the image display device, in the range that does not cover the optical path of the bending angle from the optical path, such as making the refractive optical lens 58 as thin as possible to the convex surface Distance and distance g or distance. Set the distance V as close to the thickness as the thickness limit value. 3. In order to suppress the height of the lower part of the screen to the minimum, the number is 2. The optical path lens 5 from the reflection path 59 to the convex mirror 60. Point P of 8 is set as close as possible to the optical path. Set the distance f as if the refracted light is a distance g or distance C as a thickness limit. And 496999 V. Description of the invention (53) In addition, the self-refractive optical lens 58 is deleted to include The part (non-transmissive part) where the point P does not pass, when the point P is close to the light path from the optical path bending mirror 59 to the convex mirror 60, and the optical path from the light path 59 to the convex mirror 60 is not deleted. Compared with, the lens 58 is closer. Also, for example, as shown in Figure! Or Figure 4, the reflecting surfaces of the two convex mirrors project light onto the screen, and only the convex surface = the bottom = the reflective surface is projected. Therefore, for example, as shown in Figure 42 (c) The convex mirror ⑽ is shown in the figure. If the structure is cut off, there is no reflection on the screen. Non-reflective part), the convex mirror is small in structure, which can reduce the cost of the image display device, and the structural space inside the image display device. In addition, it is also ::: cut into two halves with a convex lens, and then- Waiting for eight Image display F ¥, 讦 1 Applies two convex mirrors of the first class to 2 sets ~ The display display can be used to intersperse the process of image display device. It is stated in the present invention that the compensation for distortion aberration = refraction optics The lens 58 or the optical path f-curve mirror 59, convex = vertical, are arranged after the shape of the component, and it is necessary to maintain the structure of each and accurately form the optical path. Therefore, let the lens system 74 'reflect the refractive optical lens with a curved optical path. Mirror 59 = holding mechanism! Holding into a body. By doing so, the optical path between the two precision manufacturing constituent elements of the stationary phase convex mirror 60, from the optical quarter system, becomes stress or various environmental conditions (,, w w the outside The applied lens 58, the reflector, and the convex surface are different from each other, and the 'refraction optics' can be obtained to make the imaging device $ = the relationship is difficult to change...., That is, only the refraction is maintained by the holding mechanism; 2103-3823 -PF; AHDDUB.ptd page 56 496999 5. Description of the invention (54) The lens 58 and the convex mirror 60 are also available. As described in Example 7, instead of arranging the optical path bending mirror 59 between the refractive optical lens 58 and the convex mirror 60, it is provided between the first lens device and the second lens device constituting the fold lens 58. Light path reflector: The light path can be bent to reduce the thickness of the image display device. Fig. 44 is a diagram showing the structure of the image display device at this time. The same symbol is assigned to the same or equivalent structure as ^ 42. The first lens device of the light-transmitting and refracting optical lens 58 from the micro-mirror device not shown in the figure is reflected by the optical path bending mirror 59, and then the second lens of the transflective optical lens 58 travels toward the convex mirror 60. In this case, the distance g is the longest distance from the convex mirror installation surface to the refractive optical lens. In addition, in order to minimize the height of the lower part of the screen, which is the distance from the lower end of the screen 18 to the optical axis 61, the reflected light 75 to the convex mirror 60 at the lower end of the screen 8 should be set as close as possible. The low position of the optical axis 61 makes it more advantageous to keep the refractive optical lens 58 as far away from the convex mirror 60 as possible. In particular, when the highest portion R of the exit surface of the reflected light 75 from the self-refractive optical lens 58 passes through the low position, the optical path is blocked by the refractive optical lens 58. Therefore, the shortest distance a from the convex mirror installation surface to the refractive optical lens 58 is arranged as long as possible within a range where the distance g does not exceed the thickness. From the above conditions, in the case of FIG. 44, there is an optimal value of the distance f from the convex mirror installation surface to the projection of the refractive optical lens 58. The angle of bend of the optical path 0 is the same as in the case of using an optical path curved mirror between the lens and the convex mirror. From the viewpoint of thinning, the value should be made as small as possible. However, when the bending angle &lt; 9 is too small, the first lens device is blocked

2103-3823-PF: AHDDUB.ptd page 57 496999

Light path Figure 44 Bend the reflector to the second lens unit A l ^, and the light path of the brother is straight. Therefore, it is known that there is also a bending angle (the optimal value of 9). In addition, in Embodiments 7 and 10, instead of Xing Youyi, this is a nine-way bending mirror, so that the road bending device can also be used. The same effect is obtained. Example 1 In the present Example 11, the diameter of the incident light side and the emitted light side of the refracting optical lens from the micromirror device to the reflecting mirror is explained to be greater than the center of the lens. The small part constitutes an optical system that satisfies the Petzval condition and is favorable for bending conditions. Fig. 4 and 5 are structural diagrams showing an image display device according to Example 11 of the present invention. As shown in Fig. 4, 5 and 14 series of micro-mirror devices, 76 series of refractive optical lenses (refractive optics), 77 series of convex mirrors with positive Petzval and contributing components, and 78 series of refractive optical lenses The optical axis shared by the 76 and the convex mirror 77, 79 is a side ray of light traveling from the micro-mirror device η to the convex mirror 7 7. The refracting optical lens 7 6 '8 0 is arranged at a high position of the side ray 79. Positive lens with positive power 81 and 82 are the incident-side lens group and the outgoing-side lens group of the positive lens 80, and the light from the micro-mirror device 14 passes through the incident-side lens group 81, the positive lens 80, and the outgoing-side lens group 8 2 in this order. Convex mirror 77. As described in Example 5, since the convex mirror 7 7 has a positive Petzva 1 and a contribution component, the Petzva 1 and the projection optical system as a whole easily become positive values, and an image is generated. The surface is curved. Therefore, if the power of the positive lens 80 with positive power constituting the refractive optical lens 76 is made as much as possible,

2103-3823-PF; AHDDUB.ptd page 58 ^ 6999 V. Description of the invention (56) &quot; &quot; The important point of this embodiment is that the positive lens 80 is arranged at a high position of the side light 79. That is, considering the Petzval condition, make the power of the positive lens 80 as small as possible, and the effect of the lens function of the positive lens 80 also becomes smaller. However, in the position of the small power positive lens 80, if This makes it easy to select the heights of the light rays on the side of the light diffusion viewed from the optical axis, and the correspondence between the minute areas of the incident surface and the incident 2 surface of the positive lens 80 and the light rays transmitted through the minute areas. Therefore, the shape of the entrance surface and the exit surface of the positive lens 80 that transmits light can be designed in more detail, so that the lens function of the low power positive lens 80 can be sufficiently effective. Therefore, in contrast to the embodiment 9 in which the negative lens 72 is disposed at a lower position of the side light 71 so that the lens effect can be almost ignored, the positive lens 8 having a positive small power is disposed on the side light. At a height of 79, the lens effect of the positive lens 80 will not be jeopardized, and the axial zva (pe ^ v &amp; 1) and increase can be suppressed. This will be specifically described using FIG. 45. In FIG. 45, the positive lens 80 at the center of the refractive optical lens 76 is a positive lens with positive power in the eleventh embodiment, and is disposed at a high position of the light rays 79 on the side. By providing the incident-side transparent group 81, and the outgoing-side lens group 82 of the positive lens 80, a structure in which light rays are formed on the sides of the positive lens 80 is used. Fig. 46 is a diagram showing a numerical example 11A of the eleventh embodiment. The elementary systems of Fig. 46 are 0 · 74ππη (focal distance at a wavelength of 546 · 1ηπ), NA = 0 numerical aperture on the micromirror device side), and Yb = 1 4 · 2mm (the object height on the micromirror device side) ), M = 86 · 3 (projection magnification). Aspheric shape &amp; shape in Figure 46

496999 V. Description of the invention (57) The meaning is the same as that of the numerical example 6A. Verifying the numerical calculation results, if the height of the side light 79 of the light entering the refractive optical lens 76 is ^, and the maximum height of the side light 79 of the light passing through the positive lens 80 at the center of the refractive optical lens 76 is hm, The height of the side rays 79 of the light emitted from the self-refracting optical lens 76 is ", and these M,-, and ho satisfy the relationship of 1.05hi &lt; hm &lt; 3hi and 0.3hi &lt; h0 &lt; hi. When hi, hm, ho, and h0 satisfy the above two inequalities, the structure shown in FIG. 45 reduces the diameter of the lens at the exit portion, except for the Petzval condition described above. Because it is implemented, the description shows that the path from the optical path bending device to the reflection part is not covered, and the optical path is curved and reflected; 3, the larger case is closer to the optical lens 80 as shown in the numerical examples described later. There is also a margin. In addition, a positive mirror configuration is also possible. Values ... ⑽ shown in Figure 53 'use complex number ml4: = power through the thin through, the door is controlled by the edge of the light section: the height of the configuration has a positive increase And the power of the positive lens 80 is changed, 丨, I f, Per k ^^ 1) Function, can be suppressed.

2103-3823-PF; AHDDUB.ptd Page 60 496999 V. Description of the invention (58) The height ho of the light 79 satisfies the relationship of 105hi &lt; hm &lt; 3hi and (K3hi &lt; ho &hi; hi), which can suppress the projection optical system. The positive Petzva 1 and the contribution component 'get the effect of forming an image display device that can reduce the curvature of the image plane.' Also, the relationship of 1.05hi &lt; hm &lt; 3hi and 0.3hi &lt; ho &hi; The lens diameter of the exit portion of the refractive optical lens 76 is reduced to obtain an effect of forming an image display device having a margin in the insertion range of the optical path bending mirror. Example 1 2 In Example 4, the micromirror device 14 The effective display surface is shifted and eccentrically arranged outside the optical axis 44 of the odd-numbered aspheric surface, avoiding the reflection / transmission of the central portion (point on the optical axis) of the odd-numbered aspheric surface, so that the projection beam (light image signal) To the screen 18. Since the aspheric surface can be used an odd number of times since the vicinity of the center of the optical axis is not used, the degree of freedom of the aspheric convex mirror is improved, and the performance is improved. However, in this embodiment 12, it will be explained that the Light of mouth P The structure in which the imaging position in the axial direction is shifted from the imaging position in the optical axis direction at the center of the optical axis is an example of the degree of freedom of the optical system and the performance is improved. Take 1 mound ^ Figure 47 shows the imaging of the general optical system The relationship diagram.

In the predecessor system of Figure 47, the imaging position is designed with the optical axis center When the rabbit takes a plane perpendicular to the optical axis and uses it as the imaging surface 85, the axis is outside the axis: ^

2103-3823-PF: AHDDUB.ptd Page 61

V. Description of the invention (59) The image positions 86A and 86B are both located on the imaging surface 85. However, in ^, it is difficult to obtain the imaging position in the same plane. The angle of the imaging position is small, but the image plane is curved. For the countermeasures, it is explained that a large amount, 9, 11 and so on indicate that the method of Petzva (Petzva implements the conditions of Example 5 and reduces the curvature of the image plane. 1) The optical system of the multiplier is implemented in this implementation. Example 12, because the center of the optical axis is not used, the image position is different from the actual imaging position outside the axis. It is also an example of the optical system of the image plane f-curve, 87 series refracting optics = I Figure 48 surface mirror, 89 The curved image plane, 90A and 90B are ^ 轴 convex outside the axis as shown in Figure 48, focusing on the allowable = position. The image plane f-curve is the focus of this embodiment 12. According to the following from Petzval (PetZval) conditions of the lens, depending on the composition of the widening of the degree of dislocation. Therefore, the manufacturing conditions, the design of the self-help * easy to pay more imaging performance. Τ 'right according to this embodiment 12, eclipse γ also ▲ The imaging position of Laoshan avoids the imaging position around the optical axis. 2 The design of the optical lens 87 μ 々 ^ ^ The location of the image is 1,000, and the imaging performance of refraction is ^ #The degree of freedom is increased, and it can be composed to have Excellent imaging properties This shirt is like the effect of the display device in Example 13 except that The method of reducing image surface bending shown in Example 5 can reduce the image surface bending. As described in ^ '4, the shape of the edge warp is large, and the shape I becomes When the &amp; i test of the central part of the circle is on the local curvature of the convex mirror, the curvature of the optical axis and the brother is convex, and the curvature of the convex mirror of the warped part

496999 Fifth, the description of the invention (60) also becomes concave. Because the light is collected in the mirror, the light emitted by the optical part is scattered. When focusing on the optical axis, it can be easy and difficult. In other words, a large image plane curvature has a warping of a portion of the refractive optical lens on the image plane curvature. FIG. In FIG. 49, 91 warped convex mirrors refract the light emitted from the optical lens 91, 9 6 relative to the vicinity of the optical axis 9 1 relative to the peripheral self-refracting optics, and 9 5 and 9 7 are emitted. of. The relationship between the mirror 93 here shows that the convex curvature that compensates for the distortion aberration is imaged on the silver center at the center of the optical axis. It is speculated that the design is in general use. Therefore, the effect is suppressed. The exit pupil has the following reasons: the actual system of the present invention is refracting optics; 9 3 is an improvement and a convex mirror 9 2 is an exiting light at the peripheral portion 9 5 is an exiting light 9 6 is an exiting light lens 9 1 is an exiting peripheral portion. As shown in Figure 4-9, the emitted light 9 6 only needs to diverge the light from the reflecting mirror. On the concave curtain, the light entering the convex mirror needs to converge, and the lens condensing at the peripheral part is also refracting at the peripheral part. In the case of the refractive optical lens, the warping of the peripheral portion of the convex lens in this example 13 indicates pupil aberration, and the convex surface can be suppressed. The lens (refractive optical portion) of the image display device of Example 13 is g 2 The convex mirror of the peripheral charm, the common optical axis of 9 3, 9 5 series of outgoing light, 9 7 series of refracting optics exit pupil, 9 8 series of refracting optics exit pupil '9 9 series of self-emission 0 light as shown in Figure 49 After passing the light exit 99, the self-emission light 96 and the convex mirror 92 are reflected by the convex mirror 92, and the exit pupil can be at the position of 97. The self-refraction of curvature needs to be generated. Qu Zaiyi by making the structure around the mirror Department periphery 94 of the lens 91 is attached to the optical axis based optical lens exit pupil 97 attached to shaft 94 into a convex surface and the exit pupil to fill it

2103-3823-PF; AHDDUB.ptd page 63 496999 V. Description of the invention (61) 'It becomes a shape that satisfies no warpage like a convex mirror 93 and the emitted light 96 is reflected by the convex mirror 9 3 to compensate for the distortion aberration, Just as the exit pupil 98, the exit pupil 9 7 near the center of the optical axis 9 4 and the exit light from the peripheral part 部 μ are intentionally staggered as shown in FIG. 4 9. As described above, by adjusting the incident position and the incident angle of the light to the convex mirror 93, it is possible to suppress the warpage at the end like the convex mirror 93, and the effect of suppressing the curvature of the image is obtained. In addition, this feature is a feature recognized in all the numerical examples described above. Example 14 In this Example 14, a method for improving the imaging performance by allowing distortion aberration near the center of the optical axis of the projection optical section will be described.

Fig. 5 is a diagram showing the structure of an image display device according to Embodiment 14 of the present invention. Fig. 2 = Fig. 50, 100 is a screen, and 100 is a projection optical system and a light axis not shown in the figure. 102 indicates the largest range where the circle centered on the optical axis ιm only intersects at the bottom edge of the screen 100. Aberrations occur around the screen::, t performance. It is possible to reduce these defects. Large or small defects are required. A reduced by 4 as much as possible

In the case of the central circle of the day, as shown in the wide circumference 102, the range where the other side does not intersect with the optical axis 101 is that the absolute value of the intersection with the bottom edge of the screen 100 is larger than the circle. The area of the distortion aberration occurring on the optical side suppresses the absolute value of the distortion aberration

V. Description of the invention (62) is small, and the distortion of the distortion aberration can be formed into a correct rectangle by 3 sides. Θ8, the bottom edge of the screen 100, its ▲ V% shape image. Also, the distortion occurs with respect to the distortion aberrations caused by and. That is, the ratio of the twist distance is defined as the actual amount of distortion of the optical system is closer. The value of the aberration is the same. The distortion of the distance from the optical axis is the same for the interior of the day surface. From a visual point of view, the image The outermost peripheral part is deformed and the original image is difficult to distinguish. According to the present invention, the screen can be easily discerned, and the curve becomes a curve at the boundary portion of the day plane near the optical axis. If it is, but because the distortion from the optical axis to this $ edge occurs, the relative deformation of the line that loses the edge is small, so the distance between them is short. Compared with other edges, if there is an optical axis on the edge, the The effect is difficult to turn into a curve. In addition, this feature is combined in the display without losing linearity. effect. FIG. 51 shows a structure with a plurality of units. The construction is particularly illustrated. In Fig. 51, the projection optics "100A ~ 101F are each image display axis", which is not shown in the diagram of the device of the image display device in the case of 100A ~ 1 (f0F ^), is shown in the secret system.

The element systems of Fig. 52 f = 3.31mm (focal length at a wavelength of 546 · 1ηιη), NA = 0 · 17 (numerical aperture on the side of the micromirror device), Yob = 14.65mm (height of the object on the side of the micromirror device) ), M = 8 6 · 9 6 (projection magnification). The numerical calculation results of the distortion aberration of 4A in the numerical example 1 are shown in Fig. 54. For comparison with the design of allowable distortion aberration, the distortion aberration of the numerical example 4A is shown in Figs.

In FIG. 56 and the 14-series micromirror device, 103A and 103B are respectively attached to the refractive optical lens (refracting optical section) shown in each embodiment, and the 104 series is provided with features of this embodiment 15 The convex lens (reflection part) is the optical axis shared by the refractive optical lens 103A, 103B or convex lens 104. &amp; Face mirror ι04 Since a convex mirror with a rotational symmetry centered on the optical axis 105 is cut off, the non-reflective portion 1 〇4 c is cut out to form a convex mirror 104 (Fig. 56 (b), (c), (See Example 10). The convex mirror 104 and 104F reflect the light from the refracting optical lenses 108 and 103B as the front surface of the convex mirror. The front surface of the convex mirror is provided on the back side of the front lens. . In the present invention, because the distortion aberration is compensated, the aspheric shape of the front surface 104F is designed with a detailed optical path longitudinally. When the temperature of the use environment changes, the degree of shrinkage or expansion of each part of the f convex mirror 104 is different. The microsecond change of the 04F shape affects the compensation of distortion aberrations.

Fig. 57 (a) shows the contracted convex mirror 104, and Fig. 5? (The inflated convex mirror 104.

Surface 104F '(solid line), rear surface 104 (, solid line). Because the thickness of the convex mirror 104 is equal in all parts, the front surface 104F and the shape of the front surface 104F can keep the shape change of the front surface 104F from environmental temperature changes. Another method for the convex mirror 104 is to form a low-reflection surface 104L and a high-reflection surface 104H near the optical axis 105 of the front 104F (Fig. 56). The reflectance of the low-reflection surface 104L is set to be much lower than that of the high-reflection surface 104 * 1. The convex mirror 104 of the image display device of the present invention in which the micromirror device 14 is eccentrically arranged with respect to the optical axis 105 is not used near the optical axis 105 of the front i04F (not the front surface of the projection). The screen or the reflection of light from a flat mirror 'is provided with a low-reflection surface 104L and a high-reflection surface 10 4 Η near the optical axis 105 of the front surface 104F. Near the optical axis 105 of the front 104F, for example, in the cross-sectional view of FIG. 56 (a) including the optical axis 105 and orthogonal to the X axis, it corresponds to the closest optical axis 1 passing through the refractive optical lenses 103B to 104. The ray 106 of 5 is lower than the reflection point 10 6 P of the front 104F. The low-reflection surface 1 0 4 L and the high-reflection surface 1 0 4 Η are not aspheric shapes, but are on a small plane orthogonal to the optical axis 1 〇5 of a circular (semi-circular) shape centered on the optical axis 105. form. When the distance from the intersection of the front 1 0 4 F and the optical axis 1 0 5 to the reflection point 1 〇 6 ρ is R, the values rL and rH smaller than R are taken as the low reflection surface 104L and the local reflection surface 104H. Concentric circles (semicircles) of radius' and centered on the optical axis 105 respectively form a low reflection surface 104 L and a high reflection surface 104 mm. Since it is set that rL> rH ', the south reflecting surface 104' is located inside the low reflecting surface 104L, the high reflecting surface 104H is closer to the optical axis 105 than the low reflecting surface 104L. The low-reflection surface 104L and the high-reflection surface are provided in the convex mirror 104

It can make the alignment adjustment of the assembly process in the image display device 104H, which is easy. Fig. 58 and Fig. 58 are diagrams showing the alignment adjustment method using the convex mirror 104. Fig. 56 is the same as the number table, and the structure is not the same. In Fig. 58, the 1G7 series outputs high-permeability laser light) ..., the m series only passes the laser light from the laser 107, and then the laser light from the back protects the laser 107, and it is suppressed 1λλ- 1HQ ^ ^ ^ 耵 1 (^ 之 ^ origin, 109 is a half mirror located between the isolation mirror 108 and the convex mirror 104, and u0 is a detector that detects the power of the laser light from the half mirror 109. In addition, the arrows assigned to the symbols 系 and 112 are the laser light of the way out and the circuit when the alignment is adjusted, and the two dotted lines assigned to the symbol 11 3 are false phase lights generated by the laser light 丨 丨 J, 112. First, according to the structure of Fig. 5 8 (a), the false phase optical axis 113 for the convex mirror is set. The laser light emitted from the laser parallel to the horizontal plane 107 passes through the g-ionizer 108 and the half mirror 109. Back to the convex mirror 丨 04.

Description of the invention (67) When the laser light 1 1 1 is orthogonal, because the laser light has a high linear advancement, the laser light 1 丨 1, 1 1 2 are completely consistent, and an imaginary optical axis 1 1 3 can be generated. In the case where the posture of the convex mirror 104 is greatly deviated, the laser light 1 12 reflected by the convex mirror 104 does not enter the detector 1 1 〇 and the detector 1 1 0 does not detect power through the half mirror 1 09 . In addition, the convex mirror 104 has a near-desired posture, and the low-reflection surface 104 L of the flat mirror also reflects the laser light 111 toward the half mirror 109 when the optical axis is deviated. Due to the low reflectance of the low reflection surface 104L, the power of the laser light 112 detected by the half mirror 10 09 detector 11 〇 is at a low level, and the optical axis deviation can be detected. When considering this method, it is known that the value of the radius Rh of the high reflection surface 104H may be determined as long as the allowable range of the deviation from the optical axis is determined. In addition, after the four photosensitive elements 110A, 110B, 110C, and 10D were used to divide the photosensitive surface of the detector 110 into a "field shape" (a matrix of two columns and two rows, FIG. 58 (c)), By calculating the difference between the output signals of the photoreceptors 110A to 110D, it is possible to detect and adjust the inclination Rx and Ry of the convex mirror 104 with high accuracy. In addition, by adding the output of the four divided photosensitive elements 110A to 110D, the total optical power incident on the photosensitive elements can also be obtained, and the optical axis deviations Mx and My can also be detected. Therefore, by adopting this structure, comprehensive adjustment of Mx, My, Rx, and Ry can be performed. Then, by finely adjusting the posture of the convex mirror 104 by monitoring the laser light detected by the detector 110, an imaginary optical axis 113 based on the laser light m, 112 can be generated. Secondly, the alignment adjustment of the refractive optical lenses 103A and 103B is performed according to the structure of FIG. 58 (b). Refraction optical lenses 103A and 103B are inserted into the structure that produces the imaginary optical axis 1 1 3 of Fig. 5 (a). In this case, also when refraction

Description of the invention (68) When the postures of the optical lenses 103A and 103B become desired, the laser light 111 and 112 pass through the refractive optical lenses 103A and 103B &lt; That is, when the laser light 111 and 112 pass through the centers of the refracting optical lenses 103 and 103B orthogonally, since the lens effects of the refracting optical lenses 103A and 103β on the laser light 1 12 are not generated, it is obtained at the detector 1 1 〇 Maximum power. This desired state corresponds to the case where the optical axes of the refractive optical lenses 103A, 103B and the virtual optical axis 1 1 3 are the same. ~ As shown above, according to this embodiment 15, if the convex mirror 104 having the same thickness from the front 104F to the rear 104R is included, the shape change of the front surface 104F with respect to the temperature change can be suppressed, and the image display can be improved. Install the environment characteristics. ~ Also, if according to this embodiment 15, the convex mirror 丨 〇4 includes a low-reflection surface i04L located near the optical axis 105 of the front 104F and closer to the front 104 than the low-reflection $ 1, 104L. The optical axis 1 of F has a high reflection surface 1 04H with a tolerance range of optical axis deviation, and a virtual optical axis 1 1 3 can be generated by using the power monitor of the detector and calculation processing to obtain an assembly in the image display device. The process can easily perform the alignment adjustment effect of the refractive optical lenses 103A and 103B. &quot; Positive Embodiment 16 Structure of the device Fig. 5-9 shows an image display of Embodiment 16 of the present invention. The illustration of the illumination source system, flat mirror, or screen is omitted in Fig. 59'14. Micro-mirror device (transport device), U4 is a glass cover (transport device) that protects the reflective surface of the micro-mirror device 14, 1 1 5 It is a compensation glass that compensates for the change in optical thickness of the glass cover 1 1 4 (transport equipment

Refractive optical lenses (refractive optical lenses 76, convex surfaces) '7 6 and 7 7 are respectively attached to the optical axis shown in the embodiments) and convex mirrors (reflecting portions), 7 8 are optical axes of the folding mirror 7 7. A glass cover 114 composed of a plurality of small mirrors for protecting a reflecting surface is assembled in the micro-mirror device 14. The figure from the figure consisting of a light emitting chirp, a parabolic mirror, and a condenser lens, etc. is not shown in "Illumination". The source system m is incident on the reflecting surface through a glass cover 114. In addition, the light whose intensity has been adjusted by the reflecting surface passes through the glass cover 114 and then goes to the refractive optical lens 76 and the convex mirror 77. In addition, the thickness of the glass cover 114 is not limited to a reference value that is always fixed, and is manufactured within a range of a so-called tolerance that is the difference between the maximum dimension thickness and the minimum dimension thickness. In addition, the case where the reference value of the thickness is changed in the specifications in the future is also assumed. Because the light used by the image display device must pass through the thickness of the glass cover 114 'or the change in the thickness of the reference value, the thickness change caused by the change in the thickness of the glass cover. Individual thickness of 114 varies. In the present embodiment 16, in order to compensate for the thickness variation of the glass cover 114, a compensation glass 115 is provided between an illumination light source system or a refractive optical lens 76 and a glass cover 114 (not shown). The method for compensating the individual difference in the thickness of the cover glass 114 using the compensation glass 115 is described below using FIG. 60. Fig. 60 is a diagram showing the relationship between the thickness of the glass cover 丨 4 and the thickness of the compensation glass 丨 5. Here, in order to simplify the description, it is assumed that the refractive index of the glass cover 丨 4 is the same as the refractive index n 2 of the supplementary glass 115 (set η 1 = η 2 = η), but as shown below, the refractive index nl, η2 may be different.

2103-3823-PF; AHDDUB.ptd Page 72 V. Description of the invention (70) * Reference state Fig. 60 (a) shows the case where the thickness u of the glass cover 114 is a reference value. At this time, light is exchanged through the compensation glass 5 with a thickness t2 = T2 and the micro-mirror device 14 of the group. Therefore, the light passes through a glass medium having a thickness of t-Tl + T2 and a refractive index n. It can be regarded as a thickness pudding. "The glass medium with the ratio η exists. 'Design illumination light source system or refractive optical lens 76, convex mirror 77 and other optical systems. * Compensation example 1', j 60 (b) represents the glass cover 114. The thickness t is shifted from the reference value η by two _ΔΔT (ΔT contains positive and negative signs) to become T1 + ΔT. In this case, the compensation glass 115 with thickness t2 = T2-δτ and the micro-mirror with glass cover 114 assembled The device 14 exchanges light. That is, the total value of 12T 2 ΔT due to the thickness bTl + ΔΤ of the glass cover 114 and the thickness of the compensation glass 115 is the same thickness as the reference state t = τ 1 + T2, and the glass is assembled The micromirror device of the cover 丨 4 The light exchanged by 4 passes through the glass medium with the thickness t = Tl + T2 and the refractive index n at the specific price. Therefore, does it change due to the individual differences in the thickness tl of the glass cover 114? D. By changing the thickness 12 of the glass cover 11 4 to offset the change Δτ, it is not necessary to change the design of the optical system using the reference state. 13 * Compensation example 2 Figure 60 (c) shows that the thickness t of the glass cover 114 is in the specification When the reference value τι is changed to the reference value T3. At this time, Consider the compensation example as follows, the light is exchanged via the thickness t2 = T2 — (T3 — T1) = T3 — ΔTT and the micromirror device 4 assembled with the glass cover 丨 4.

Same as Example 1 of the 4th member, because the thickness of the glass cover 11 4 11 = τ 1 + (T 3 — T1) = Τ1 + ΔΤ and the thickness t2 of the compensation glass 115 = 2 _ (Τ3 _Τ1) = Τ2 — Δτ The value becomes the same thickness t = T1 + T2 as the reference state, and the light exchanged with the micro-mirror device 14 passes through the glass medium having the equivalent thickness t = T1 + T2 and the refractive index ^. Therefore, although the thickness deviation caused by changing the thickness t1 of the cover glass 114 from the reference value τι to the reference value T3 occurs, by changing the thickness t2 of the cover glass 114 to offset the thickness deviation Δ ?, it is not necessary to change the design. Optical system using the reference state. It is known from the above reference states and compensation examples 1 and 2 that in this embodiment 16, according to the increase or decrease in the change (or thickness deviation) Δτ of the reference value n provided by the thickness t1 of the glass cover 114, the glass 15 will be compensated. The reference value T 2 of the thickness t2 has only the opposite decrement (or thickness deviation) Δ τ, because the total value t = Tl + T2 becomes a fixed value, which can be regarded as the reflection surface of the micromirror device 14 &quot; ί The assembled thickness t = Τ1 + T 2. The glass medium with the refractive index η will not be affected by the variation (or thickness deviation). The optical system in the reference state can be directly used. Of course, the micro-mirror device 14 is not limited, and the present embodiment 6 can also be applied to other optical space modulation elements such as liquid crystal. In the above, it is considered that the glass cover 11 4 and the compensation glass 5 have the same refractive index η, but the glass cover 1 1 4 and the compensation glass 1 1 5 each have different refractive indices η 1 and η 2 and It is also considered that the optical thicknesses of the refractive indexes η 1 and η 2 are more general. That is, considering the optical thickness of the glass cover 114 / / and the optical thickness t2 / n2 of the compensation glass Η5, so that the compensation glass 1 1 is determined as if the condition rtl / nl + t2 / n2 is satisfied. The thickness is 5 and the refractive index is n 1. According to

The external emissivity n 1 is again and again, and the right is maintained on the refracting optical lens 76 (the incident side of the lens barrel that refracts light and wind (the side of the micro-mirror device 14) :): The structure of Wei Li 11 5 on the picture (compensating glass (Removable mechanism), and replacement of the broken glass installation compensation or thickness change is replaced by the thickness of the nth thickness change <numerical example 16A &gt; Figs. 6 and 62 are diagrams each showing a numerical example of a numerical example 6A. The same symbols as in Figs. 45 and 49 indicate that they are the same or inform each other. The elements of Fig. 61 are 3.39mm (focal length at a wavelength of 546 · lnm), N Fan 〇 · 17 (numerical aperture on the side of the micromirror device), Y〇b = 14.65_ (微 反 ^ Device-side object Height), M = 86 · 96 (projection magnification). Calculated because the glass cover 丨 spoon contains the compensation glass 115, shown in Figure 6 2 comprehensively. In the numerical data shown in 61, the sum of the glass cover 丨 4 and the compensation glass 丨 5 indicates the thickness of the second surface 4.5 mm. For example, it is assumed that the standard thickness of the glass cover is 3 mm, and the thickness of the compensation glass is 1.5 mm, and then the aberration compensation is performed. ",", As shown above, "If according to this embodiment 丨 6, between the glass cover 11 4 and the refractive optical lens 76 or the illumination light source 组装 assembled on the reflecting surface of the micro-mirror device 1 4" 2. The optical thickness of the glass cover 11 4 which is increased or decreased due to manufacturing tolerances or design changes, and the compensation glass 11 5 is designed to have the opposite optical thickness of the change, which makes the micro-mirror device The reflecting surface of 1 4 exchanges light to offset the change in thickness of the glass cover 11 4. It can be seen as protecting the micro-reflection with a medium that always has a fixed optical thickness.

In this embodiment 17, focusing on the space s in the configuration space of the light-concentration = academic department, etc., increases the degree of the lower part of the screen 117, because the light corresponding to the light 119, 120 and the point R is in the space S When arranging the components of the condenser optics, if you take care to avoid blocking the light 119, 120, all other light will not be blocked.

In addition, 127 and 128 are the second optical path bending mirror (second optical path bending device) and the third optical path and curved mirror (third optical path bending device), which are characteristic of the 17th embodiment. The objective lens (transmission device) that the light of the lens 126 has the same main line direction and enters the micro-mirror device (transmission device, reflective image data application unit) 14. The light from the relay lens 126 is sequentially reflected by the second and third optical path bending mirrors 1 2 7 and 1 2 8 and then goes to the objective lens 1 2 9. The light-concentrating optical system that focuses light toward the micro-mirror device 14 is composed of an illumination light source system 1 2 3, a color wheel 1 2 4, a rod-shaped integrator 1 2 5, a relay lens 1 2 6, and a second optical path curved and reflected. The mirror 127 is composed of a third optical path curved reflecting mirror 28 and an objective lens 29. In particular, the illumination light source system 1 2 3, the color wheel 1 2 4, the rod integrator 125, and the relay lens 126 are referred to as the main parts of the condensing optical system. 1 3 0 is the optical axis shared by the main parts of the condensing optical system, 1 3 1 is the remaining space of the image display device 11 6 and constitutes a general image display device.

In FIG. 64 ′, the main part of the condensing optical system is arranged in the space S such that its optical axis 130 is parallel to the bottom surface 118 of the image display device 116 and the photosensitive surface of the screen 18. One of the reasons is shown in FIG. In the case where the illumination light source with the optical axis 1 3 0 on the horizontal plane 1 2 3 is inclined to become the illumination light source 123A with the optical axis 1 3 〇a, the misalignment angle 0 of the optical axis 130 and the optical axis 130A exceeds a predetermined value (for example, 1 5.), the internal temperature distribution of the luminous body 丨 23 constituting the illumination light source system 22 deviates from the prescribed state because the life of the illumination light source system 1 2 3 is shortened.

In the rotation centered on the optical axis 130, the problem 0 illumination light source system 1 2 3 will not occur. It is limited to the shown, because the image display device 116 is not only the &amp; surface 118, it is horizontally used (Figure 6 is used as The image used to hang on the wall shows a positive shape and a positive shape. Another example ^ η 〇 ^ If the image display device is not used, the use of evil is made from the horizontal plane to the bottom plane and the bottom plane \ 1 (Figure 6 7 (b )), Or the use form that tilted slightly from the water surface 118 after being turned upside down (Figure 67 (c)), etc. Town: / 2 or two reasons other than 'In order to meet the size of the image display device 116 $ axis direction Minimization) or the height of the lower part 117 of the screen, and the minimization of the size of the lower part 117 in the axial direction). By doing so, as shown in Figs. 67 (b) and (c), the case where the Λί image display device 116 is tilted is also caused by the rotation of the optical axis 130 as the center of the illumination source system, which will not damage it. Among the 1 ^ 23 brothers, the lighting source can adapt to various usage forms of the image display device 16. Here: As shown in Fig. 6 and 5, in order to avoid blocking the light (inclined portion) from the convex mirror 60 to the screen 18, a large component is arranged in a region closer to the B_β 'plane than the A-A' plane. As described in Embodiments 7 and 10, a plane mirror 22 is provided in parallel with the screen 18, and the refractive optical lens 58 and the micro-reflector are determined from the positions of the light path bending mirror 59 and the convex mirror 60 which are appropriately arranged with respect to the plane mirror 22.

Therefore, in order to enter the light from the main part of the condensing optical system arranged in the space s into the micro-mirror device 4, the second and third optical path bending mirrors 127 and 127 are provided between the relay lens 126 and the objective lens 129. 128 as the medium of light.

Description of the invention (77) The second optical path is located at a higher position than the third optical path curved mirror 丨 28, and the curved reflective mirror 1 2 7 is set at a position as low as possible. In the positions of the second and second optical path curved mirrors 127 and 128, the reason for selecting the relay lens 1 2 6 and the objective lens 1 2 9 is determined by the mutual positional relationship of other constituent elements according to optical conditions such as imaging By adjusting the focal length of the relay lens 1 2 6 and the focal length of the objective lens 1 2 9, the length of the optical path from the relay lens 126 to the objective lens 129 can be appropriately determined.

The three screw fixing portions 136 ~ 138 are fixed as shown in the following description; V ,: 496999 V. Description of the invention (82) — 'Keep the convex mirror 1 34 on the image display device. In addition,' It is desirable to suppress the deformation of the reflecting surface of the convex mirror 134 to a minimum, and to form the screw fixing portions 136 to 138 and the screw holes simultaneously with the convex mirror 134 1 36H ~ 138Ϊ1. The first screw fixing portion 136 is provided near the optical axis 135. That is, when the front view (FIG. 70 (a)) looks from the direction of the optical axis 135, the convex mirror 134 looks rectangular, and the first screw The fixed portion 136 is configured to be the convex mirror closest to the front side with the "and optical axis 135" The point below 35mm (Figure 70 (a) ix), and the eccentric distance from the optical axis 135 to the center of the screw hole 13611 is the shortest on this bottom. The allowable range of the eccentric distance will be described later. The first screw fixing portion 136 utilizes a convex mirror mounting mechanism (first reflecting portion mounting mechanism) fixed to the image display device. 4 40, a push ring 139W, and a nut 13 are positioned in the plane perpendicular to the optical axis 135 'of the convex mirror 134 (Pivot (Rotation axis) is fixed to the mounting surface of the convex mirror mounting mechanism 14. By using the pivot fixing, the degrees of freedom of the convex mirror 134 are all fixed except for the rotation in the direction of the push screw 139 inserted into the screw hole 136H. Because of the pivot Fixing, convex mirror Anpei mechanism 丨 40 and up to the screw hole 136H of the first screw fixing part 136 are determined by the push-pull screw 139 to determine the shape of the hole (push shape), and the push-screw 139 is installed through the convex surface. After the mechanism 140 passes through the screw hole 136H, it is locked using, for example, a washer 139 and a cap 139N. By fixing the convex mirror mounting mechanism 14 to the screw hole 136} 1 of the first screw fixing portion 136, Taper shape, may be fixed pivot exact Ding after finished screws, screws Shu taper 39 of the push pull eight remain inside the mounting mechanism 140 of the convex mirror, from the convex mirror mounting mechanism "Ο projecting knife

5. Description of the invention (83) The part shown in (83) is fixed with a washer 139W and a nut 139N. With respect to the first screw fixing portion 136, the second screw fixing portion 137 and the third screw fixing portion 138 are respectively provided on the left and right sides of the front view of the convex mirror 134 in FIG. 70 (a), so that the second screw is connected by a line segment. The area of the center point of the fixing part 37, the center point of the second screw fixing part 1 38, and the equilateral triangle formed by the apex of the convex mirror iMP should be as large as possible. Each of the second screw fixing portion 137 and the third screw fixing portion ι38 is held with respect to the convex mirror mounting mechanism of the image display device using straight screws 1 4 1 (the second reflecting portion mounting mechanism and the third reflecting portion mounting mechanism, respectively).二 之 * The mounting surface slides. Keeping sliding means that the convex mirror 134 is thermally expanded and heated. When thin, the second screw fixing portion 137 and the third screw fixing portion 138 are shifted along the surface of the convex mirror mounting mechanism 42. The ship 2 slides in two. The screw holes 137H and 138H of the second screw fixing part 137 are set larger than the screw diameter of the straight screw 141, and the mounting surface of the convex mirror mounting mechanism 丨 42 is increased.

The temperature change of the mirror 1 3 4 has the following characteristics: ▲ 5 5 Mercury Worker 1 Le Ben Guan ^ Example 18 features. Explanation The operation of the convex mirror 1 3 4 with a change in the degree of / JDL is as follows. FIG. 71 is a diagram showing the thermal expansion of the convex mirror 134 at normal temperature due to temperature changes. The same symbols as those in FIG. 70 indicate the same structure. FIG. 71 shows the convex mirror 134 under the temperature and the convex mirror 134 'that thermally expands from a temperature rise. The symbol without the symbol "," indicates the constituent elements of the convex mirror 134, and the symbol with the symbol "'" strictly indicates the constituent elements of the thermally expanded convex mirror 134. In Fig. 7 (a), the position of the first screw fixing part 丨 36 in the plane of the light 135 becomes a fixed point of stress deformation, and the stress of the shape change caused by thermal expansion acts on the other of the convex mirror 34 section. At this time, since the first screw fixing portion 1 3 Θ is set near the optical axis 1 3 at a predetermined eccentric distance, the deviation of the optical axis 1 3 5 can be suppressed to a minimum. In addition, the stress generated when the temperature is changed to thermal expansion due to a change in temperature is maintained as the sliding second screw fixing portion 37 and the third screw fixing portion are offset. Fig. 7 1 (b) is an enlarged view of the third screw fixing portion at room temperature (the line of the third screw) and the third screw fixing portion 138 at the maximum thermal expansion (the solid line) is as shown above, and the straight screw 1 Compared with the screw diameter of 41, the diameter of the screw hole 138H (137H) of the second wire fixing portion 138 is made larger, = the screw screw fixing portion 1 3 8 slides the stomach along the mounting surface of the convex mirror mounting mechanism 1 4 2 — The front surface 1 34F of the front mirror 1 34 is shaped at a normal temperature and after thermal expansion, and can be shaped in a convex shape, which can suppress the optical properties of the image display device against temperature changes. Of course, the same thought can be given to the occurrence of heat shrinkage. heart

According to Figure 7 1 (c), the screw

2103-3823-PF; AHDDUB.ptd Page 87 496999 V. Description of the invention (85) The relative size of the wire diameter is based on the temperature specification of the image display device, from the screw hole 138H when it expands to the maximum, and when it shrinks to the minimum. The position (movement) of the screw hole 138H can be determined. The relative sizes of the screw diameters of the screw holes 1 3 7H and the straight screws 1 4 1 can also be determined in the same way. The eccentric distance between the first screw fixing portion 1 3 6 and the convex mirror vertex 1 3 5 P can be determined as follows, for example. Fig. 72 is a diagram for explaining the deviation angle Δ (Θ) of the vertex 1 3 5 P of the convex mirror when the convex mirror 1 34 is rotated around the first screw fixing portion of the eccentric distance EXC as a center. The same reference numerals as those in Fig. 70 indicate the same constituent elements. Since the convex mirror 1 3 4 is pivotally fixed by the first screw fixing portion 1 3 6, the position of the vertex 135P of the convex mirror of the convex mirror 134 is also determined by the first screw fixing portion 136. Therefore, in the assembly process of the image display device, the deviation angle Δ (0) of the convex mirror apex 135P occurs when the first screw fixing portion 136 is pivotally fixed, that is, as shown in FIG. 72 (a), the self-convex mirror apex 135P is used. Only the eccentric distance of the screw hole 136H of the eccentric distance is taken as the center, and the convex mirror 134 only rotates at an angle (9 o'clock due to the assembling error of the convex mirror, the deviation angle △ (0) of the convex mirror 35P in the vertical direction. Consider this, for example, by the convex mirror 1 The size of 34 or the adjustable range of the rotation error of the assembled cake is 0. The eccentric distance EXC of the first screw fixing portion 1 36 is determined so that the deviation angle △ (Θ) is within the allowable range. Now, in Fig. 72 (a) , The deviation angle △ (Θ) of the optical axis 135 can be obtained as △ (Θ) = EXC · [1 — cos (0 · ΤΓ / 180)]. According to this formula, for example, the rotation error Θ and The relationship between the deviation angle △ (0) is shown in Fig. 7 2 (b). The horizontal axis and vertical axis are respectively rotation errors Θ and deviations.

2103-3823-PF; AHDDUB.ptd Page 88 496999 V. Description of the invention (86) Angle △ (Θ) 〇 For example, set the rotation error (the adjustable range of 9 is 2deg, the maximum allowable value of the deviation angle △ (0) When it is 0.1 mm, from the curve of Fig. 72 (b), for Θ = 2deg, △ (ehO. OZmm), the first screw fixing portion 136 is made into a convex mirror 134 with an eccentric distance EXC = 20mm, which is more than 5 times sufficient. In addition, make the eccentric distance EXC 20, so that the center of the screw hole 136H and the convex mirror vertex 1 35P may be the same. Of course, in this case, the deviation angle △ (Θ) of the convex mirror vertex 1 35P does not occur. It is possible to hold the convex mirror 1 3 4 in a more ideal state. In FIG. 70, the first to third screw fixing portions 1 3 6 to 1 3 8 are fixed with screws than the convex mirror mounting mechanism 1 4 0, 1 4 2 The reason for approaching the rear 1 3 4 R side is to use the convex mirror mounting mechanism 1 4 0, 1 4 2 to maintain the shape and position of the front surface 134F with high accuracy, so that the stress of the convex mirror 134 due to temperature changes becomes the rear 1 3 4 The shape of R is changed. Therefore, it is possible to suppress the shape change of the previous 1 3 4 ρ. The convex mirror 34 which takes measures against temperature changes has been described above, but its shape is not limited to that shown in FIG. 70, for example, the convex mirror shown in FIG. 73. ^ ^ FIG. 73 is a structural change diagram of the convex mirror 134 taken with measures against temperature changes. It is a front view. The same symbols as those in FIG. 70 are the same or correspond to those in FIG. 73 (a). Instead of fixing the first screw Qiu Xinchong 1 3 6 to form a concave capital 4 4, the curved surface of the cylindrical support 145 is embedded in m ”ll. 1 a eight recesses 144. At this time, because the recesses 144 are pressed against the cylindrical support 145, the right sun μ 彳 η — 丄 is set around the recesses 144.

496999 V. Description of the invention (87) The convex mirror 134 is connected to the elastic 143 below the staggered down. In Fig. 73 (b) ', instead of the first screw fixing portion 36, a convex portion 146 is formed so that the convex portion 146 enters the V-groove support body 47. As in Fig. 73 (a), since the convex portion 146 is pressed against the V-groove supporting body 147, two springs 143 are provided on the left and right sides of the convex portion 146 to connect the convex mirror 134 to the lower side. In this case, if the apex 1 3 5 P of the convex mirror is located at the center of the convex portion 丨 4 6 of the arc, the eccentric distance illustrated in FIG. 7 2 becomes 0, and the mirror can be maintained in a more ideal state at 134 °. As shown in FIG. 73 (c), the second screw fixing portion 3 and the third screw fixing portion 138 can be provided on the side opposite to one of the first screw fixing portions 136, and the same as in FIG. The same effect. In addition, it is also assumed that the image display device is used upside down (refer to Example 17). At this time, as shown in the front view of FIG.箬 Fixing 4146A and 146B each fix one end of the two springs 143, and the other 4 ends are fixed w so that the convex mirror 134 can be pulled by the spring 143.

The second screw fixing portion 37 and the third screw fixing portion 38 are not limited to one each, so that two or more may be provided. Embodiment 19 Following Embodiment 18, this embodiment 19 also describes an image display device using a temperature change. Fig. 75 is a diagram showing the structure of an image display device according to the embodiment 9 of the present invention; &amp; In Figure 75, 148 series of micro-mirror devices (transmission device, image data application unit), 149 series of refractive optical lenses of each embodiment, 150 series of optical axes of refractive optical lens 149, and 151 series of micro-mirrors Device 148 or refraction: Optical base (holding mechanism) of optical system such as lens 149. The optical base ^^ is equivalent to the holding mechanism 7 4 shown in FIG. 4 (refer to Example 丨 0), and is held as a unitary body with the lens 149 or an optical path bending mirror and convex mirror not shown in the figure. Hold the micro-mirror device 148. , 152, 153 are fixed to the optical base 151 and the refractive optical lens 149

V. Description of the invention (90) Two sliding support 桎 of the sliding support. The cup stays 152 and 153 slide toward the optical axis 15 °. The 154 series is fixed on the optical base 151 and the bottom of the refracting optical lens 149 is mounted on the plate / plate = 'plate, the 155 series is fixed on the thunder, aa * a, and the celestial plate. In addition, the DC control voltage changes the light; f ::; the mounting plates 154 and 155 are located between the sliding support two moving supports ^, so that the piezoelectric it member 156 is sandwiched between the opposing faces, and the piezoelectric device 1 5 6 Keep in touch. From the micro-mirror device 1 48, $ Zhong, Zhi Dan / a-After the optical lens 149, as shown in 4: = (_ 先 景:; Shown $ face mirror, + face mirror and screen. At this time, for example, in the case of initial adjustment of the focus of the image on the screen of i τ t at room temperature, the focus of the image is misaligned due to the temperature change of the use of the image display device. This focus misalignment occurs due to the differences in the lens group and the interval between the lenses in the refractive optical lens 149, and the difference in the temperature distribution and linear expansion rate of the optical base 151 or the optical frame components on the optical base 151. The degree of thermal expansion and thermal contraction in one direction of the optical axis 150 are different, and the relative positional relationship of the 7C components of the optical system is shifted. Particularly problematic is the change in the length LG in the direction of the optical axis 15o from the micro-mirror device 148 to the refractive optical lens 149. From the results of numerical analysis and the like, it is known that the factor f has a large effect on the focus misalignment. There are two factors. One is that the value of L0, which becomes the best focus, changes due to the temperature of the lens itself. The optimal value [0 becomes 10a, and the other factor is the change in physical temperature, L0. Itself changes, the physical distance L0 becomes L0B. Here, if the temperature changes, keep calling = _ 之 关

496999 V. Description of the invention (91) system, there will be no focus misalignment. However, in the case of LOA off LOB, focus misalignment occurred. In order to compensate for the change in the length LOA-LOB, a piezoelectric element 156 is provided in Fig. 75 so that the length in the direction of the optical axis 15 can be adjusted by the control voltage. That is, the initial focus adjustment is performed in a state where the initial bias of the control voltage is applied to the piezoelectric element 156. Then, the control voltage applied to the piezoelectric element 56 is adjusted according to the temperature change of the use environment of the image display device. In this way, by changing the length in the direction of the optical axis 150 of the piezoelectric element 156, the distance between the mounting plate 1 5 4 and 1 5 5 which is in contact with the piezoelectric element 1 5 6 is changed.

At this time, the refractive optical lens 149 slides on the sliding support posts 52, 1 5 3 along the optical axis 1 50. For example, when the length L0 A — 10b becomes longer than the initial adjustment state due to a change in temperature, the control voltage is reduced to shorten the length of the piezoelectric element 156. Therefore, the 'refractive optical lens 1 4 9 slides on the sliding support column 1 5 2, 1 5 3', because the micro-mirror device is approached along the optical axis 1 50 direction, 48, the length affected by the degree k can be returned to Initial adjustment status. Conversely, when the lengths L0A-L0B become shorter, the control voltage is increased to make the length of the piezoelectric element 156 longer. Therefore, the refractive optical lens 149 is

Columns 152 and 153 slide upwards. As they move away from the micro axis along the direction of the optical axis 150, the length L of the effect of temperature change can be returned to the structure at 囷 75. The control of 15Θ can compensate for the misalignment of the focus point _ ^,, w, and the change in length L0, which can be adjusted / adjusted.

Fig. 76 is a diagram showing the structure of an image display device according to Embodiment 19 of the present invention. The same symbols as those in FIG. 70 are the same constituent elements. The illustration of the structure after the light source 糸 or the convex mirror is omitted.图 In Figure 76, 157 is a gear supporting column fixed on the optical base 151, and it is a 157G precision gear mechanism that includes a motor and other gear mechanisms and a small backlash in the direction of the optical axis. The 50 ° direction makes the refractive optical lens 49. The optical axis moves in the 50 direction. 1 58 and 1 59 series temperature sensors, the temperature sensor 58 detects the temperature T1 of the barrel of the refractive optical lens 149, and the temperature sensor 159 detects the temperature T2 of the optical base 151. Also, '1 60' is a heating cooler that heats and cools the optical base 5'1, and a Peltier element is a representative example. } 6 丨 is a control unit such as a CPU, which performs feedback control of the gear mechanism 15 7 G or the heating cooler 16 0 according to the temperatures T1 and T 2. In FIG. 75, the piezoelectric element 156 is used to adjust the length [0〇—10b, but in FIG. 76, the gear mechanism 157G is used to move the refractive optical lens 149 in the direction of the optical axis 15o, and the length LOA-LOB is adjusted. In this way, the same effect as in the case of Fig. 75 is obtained. Also, in FIG. 7 6 ′, the characteristic point is that using the temperature sensors 丨 5 8 and 丨 5 9 to sense the real-time sense, refracting the temperatures T1 and T2 of the optical lens 149 and the optical base 151, the control unit 161 controls the temperature n, 2 Perform feedback control of gear mechanism 15 7G and heating cooler 160. Now, set the linear expansion coefficient of the lens barrel of 4 9 and the linear expansion coefficient of the optical base to Pi and P2 respectively. Set the refraction in the direction of the optical axis from the light incident end to the gear support column 157 Optical lens 149 of

496999 V. Description of the invention (93) The length is L 1 (L 0 + L1 = L 2), and the temperatures of the refractive optical lens 149 and the optical base 151 set at the initial adjustment of the focus are τ0. When the image display device has a temperature slope in the use environment, and the length L 0 becomes L 0 B = L 0 + △ L 0, the temperature sensors 1 5 8 and 5 9 are respectively set to detect refractive optical lenses. 149. The temperature of the optical base 151 is n, T2 (T1 = ^ T2). At this time, the amount of change can be obtained, △ [⑽ 二. (T2—TO) —LI • pi • (T1_τ〇). In addition, the control unit 161 is made to memorize in advance Δ L0B which is the optimal L0 value for the focal point of the lens barrel temperature 71. After the ingenuity unit 161 calculates the physical change amount of the length 10, the control unit 161 adjusts the gear mechanism 57G, and adjusts the length of L0 as the optical focus moving director ΔLOB becomes zero. By doing so, the gear mechanism 157G is used to move the refracting optical lens 149 in the direction of the optical axis 150 like the offset optical focus amount ALOA — (focus compensation amount), which can be displayed on the screen independently of the temperature change in the use environment The focus of the image. Of course, like the piezoelectric element 156, the gear mechanism 157G is actuated by the control voltage. When the control unit 161 inputs the temperature from the temperature sensors 158 and 159 to 2, the gear unit is not adjusted by%, and the cooler 160. The optical base 151 is heated by 〇ρ, and the optical base ΐ5ι, 、, = f ^ service • heat shrinkage control length L2 may be used. By doing so, the temperature gradient that can be controlled can be related to the temperature change in the use environment: keep the focus of the image displayed on a screen not shown in the figure dependently. In addition, the temperature sensors 158, 159, the control unit 161, and

496999 V. Explanation of the invention (94) The temperature change countermeasures of the gear mechanism 157G and the temperature change countermeasures using the temperature sensors 158, ι59, the control unit 1 6 1 and the heating cooler 丨 6 ○ can. The number of the temperature sensors 1 58 and 1 59 is not particularly limited. The number of the same heating cooler 1 60 is not limited. The positions of the temperature sensors 5 8, 1 5 9 and 埶 cooler 160 are also not limited. . In addition, it should be a range in which the performance of the image display device does not particularly cause problems. It is also thought that the refracting optical X-ray lens 149 is heated and cooled by a heating cooler 160. In addition, the temperature sensors 158 and 159 and the control unit 161 of FIG. 76 may be applied to the piezoelectric element 156 of FIG. 75. In addition, the temperatures n and T2 sensed by the 'temperature sensors 158 and 159 do not necessarily reflect the focal point of the image. A learning function is provided in the control unit 161, and it is also possible to take countermeasures against temperature changes using the sub-boiler month b. The adjuster performs the initial focus adjustment at a certain ambient temperature T3.

The length of Km memory at this time is old] 13 The same way, the initial focus adjustment is also performed under a certain environment guanidine degree Γ4 (off T3), so as to control the length [LG] T4 at this time. H161 § Self

With this, the control unit 161 interpolates the two points straight from the (T3, [L0] T3), (T4, [L focus adjustment points) to derive the interpolation relationship. Then 1 moxibustion, the control unit 1 6 1 senses with the temperature sensor After measuring the ambient temperature Tx of the device located in the actual environment ^, calculate the length for the strict production 5 = [L0] TX 'by using the interpolation relationship. After using the piezoelectric element 156 or the gear :: the length of the repairer L. (Focus compensation amount).

The relationship between the 11 best length values and temperature corresponding to "Si" is introduced into the interpolation relationship formula, and the focus compensation can correct the learning control formulas $ 、,, w for household properties, and four &amp; workers. The eye of the adjuster is one-to-one: the focus relationship causes the control unit 161 to learn the result 5 | In addition, the temperature sensing benefit in this case is set on the image display device as if it can sense the ambient temperature. Erbu ', because of the same reasons as the learning control method described above, is not an unharmed bottle of glutinous degree ΤΙ Τ2, so that the direct detection and display of the focus on the image of the shadow "and" ^ / shirt image "and the feedback control also Yes. Θ represents the structure of the image display device of Embodiment 19 of the present invention. The same symbols as in Figs. 75 and 76 are the same or equivalent components.

Description of the invention (104) The reflective surface 104H and the low reflective surface 104L are concave or the entire surface is set to a high reflective surface. The reflective convex portion 17 2 and the reflective surface of the reflective concave portion 1 7 3 are planes, and the normal of the plane is parallel to the optical axis 1 7 1. Fig. 8 is a flowchart showing an alignment adjustment method in Embodiment 20 of the present invention. 84 to 88 are diagrams showing the arrangement of the optical system constituent elements in order according to the steps of the alignment adjustment method of FIG. 83. The same reference numerals as those in FIG. 80 indicate the same constituent elements. <Step ST1: Alignment of Convex Mirror for Fixture Screen> In Figure 8 (a), set the parallel light beam emitted from the laser light source 174 and the normal line of the fixture screen (fixture display device) to be parallel . From the laser light source 174, a parallel light beam having a larger cross-sectional area than that of the reflective convex portion 172 is emitted, and the parallel light beam enters the fixture screen 176 perpendicularly through the beam splitter 175. A transmission hole (first lens hole) 176H is provided around the optical axis of the fixture screen 176 (FIG. 84 (b)) 'A part of the parallel light beam which transmitted through the beam splitter 175 is transmitted through the transmission hole 176H, and is then set on the optical base 177 (holding The mechanism, FIG. 43, refers to the reflective convex portion 17 2 of the convex mirror 170 on the embodiment 10). After the convex mirror 170 and the reflecting convex portion 17 2 reflect the parallel light beams, the parallel light beams toward and away from the parallel light beams are transmitted through the transmission holes 176H.

Then, the alignment adjustment of the light path bending mirror 170 (see FIG. 23 and the like, with reference to Example 7 and 10) of the convex mirror 170 is performed (see FIG. 8 5). In FIG. 85, a parallel light beam having a cross-sectional area larger than that of the reflective convex portion 172 is emitted from the laser light source 174 through the beam splitter 175, and then is reflected toward the reflective convex portion 172 by the optical path bending mirror 181 disposed at a predetermined position. Since the reflecting convex portion 172 becomes a reflecting surface smaller than the incident parallel light beam, only a part of the parallel light beam reflects toward the optical path bending mirror 1 8 1. The parallel light beam from the reflecting convex portion 17 2 is reflected by the optical path bending mirror 1 § 1 and then is reflected to the beam splitter 1 7 5 and is detected by a four-division detector 1 7 9 through a condenser lens 1 7 8.

The illustration of the components of the prior learning system from the lighting source system to the convex mirror is omitted. ϋ ® In the lower part of the screen shown in Fig. 90 '192 series screen, 193 series of optical components not shown on the collection picture, 194 series by the screen 192 and the front of the silver box, 195 series is set parallel to the screen 192 " Mirror (= plane mirror 22, referring to the embodiment, 196 is the rear of the housing for storing the flat mirror 195, and 197U, 197L, and 197R are the inclined surfaces (upper inclined surface, left portion) of the upper and left and right portions of the casing of the image display device. Oblique surface, right oblique surface), the bottom surface of the 198 image display device. In the case of FIG. 90, the height of the front portion 194 of the casing is determined by the setting angle of the screen 192 in the vertical direction and the height of the lower portion 193 of the screen. The width of the front part 194 is determined by the horizontal length of the screen 192. The height and width of the rear part 196 are determined by the height and horizontal length of the flat mirror 195 in the staggered direction (but it determines the rear part of the body 1 9 6 The size is not limited to the flat mirror 195.

The parallel beams with planes ^ are defeated at f with the refracted parallel beams = highly reflective surfaces and paths and retracement ~ and there is the refraction optical mirror from the optical path ": the optical axis corresponds to 496999 i number Q. in5157 VI. The scope of applying for a patent from the second transmission hole to the ideal light car from the center of the parallel beam and the parallel beam from the high circuit steps to maintain the convex part from the lens; and set the lighting source information The imparting unit will image the photo 'through the refractive optics section and the light image # on the correction _a. The highly reflective surface sequentially reflects the parallel beams of the refractive optics section', so as to be reflected by the cavity mirror. Steps in which the bending directions of the curved reflecting mirrors facing the optical path are sequentially reflected in the same direction; and the refracted light is set after removing the hole-shaped empty mirror = ^ 5 Hai image data application department, using the image Mingyuan source section to emit $$, Xi It is also the step of displaying the normal position of the F image lens as the light image signal fixture before the shooting 2103-3823-pf1.ptc page 169
