Embodiment
Below, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The manufacturing equipment of the optical devices that one embodiment of the invention provides is described referring to figs. 1 through Fig. 3.Fig. 1 is the manufacturing equipment synoptic diagram of explanation according to the optical devices that one embodiment of the invention provided, and Fig. 2 is used to arrange the curve map of the light extraction principle of prism for explanation, and Fig. 3 is the prism unit synoptic diagram that is used to illustrate the lens optical distance;
As shown in the figure, the manufacturing equipment 1 of optical devices comprises the display part 70 of white light source 10, wavelength selection light filter 20, light quantity adjusting portion 30, optical collector 40, the stand 50 that is used to regulate prism location, light guide portion 60 and demonstration interference.As shown in Figure 3, prism unit 100 is decomposed three prisms, 110,120,130 formations of special rete (film) by having the RGB color, promptly constitute, be provided for reflecting reflection of incident light mirror 111,121,131 on the exit facet of each prism by R prism 130, G prism 110 and B prism 120.
In order correctly to measure the displacement of determination part with respect to reference light, its method is for adopting interferometer, in the present embodiment, and for the difference of measuring the light path by prism is used Michelson (michelson) interferometer.Michelson interferometer is widely used in measuring in film thickness or wavelength (spectrum) and the high resolution spectrometer, as accurate mensuration optical wavelength.50% light transmission is arranged from the primary light of light source outgoing, and remaining 50% light changes 90 degree paths and is reflected.The light in different paths is converged to a place by secondary reflection more respectively, and short of external action this moment is because of the difference of two light paths is certain, so its interference fringe can not change.But if having the variation of external environment condition as mobile mirror etc., then the phase change owing to wavelength occurs disappearing mutually or long mutually interference fringe.Therefore, can measure mobile test piece by the length of interference fringe.
If outgoing short wavelength's laser, but then owing to the interference distance that can produce interference is longer, so can reproduce interference in wide region; But, as white light when being mixed with the wavelength that comprises several scopes, but since interference distance shorter, so within the relative distance difference scope of about 3～4 μ m, can observe interference fringe.In order to make the light length by each prism inside, (optical path length) is consistent within 5 μ m error ranges promptly from the prism plane of incidence to the optical range the exit facet in the present embodiment, thereby but utilizes the short white light of interference distance.
Wavelength selects light filter 20 only to extract the light of particular range of wavelengths from the light of white light source 10 outgoing.
In the present embodiment, fixedly observe the interference of light phenomenon that reflects by G prism 110 and B prism 120 by regulating mobile B prism 120 under the state of G prism 110, and regulate mobile R prism 130 and observe the interference of light phenomenon that reflects by G prism 110 and R prism 130.Because interference is observed in the similar light of wavelength and intensity easily, thereby in order to observe the interference of light phenomenon by G prism 110 and 120 reflections of B prism, needs the light of blueness and the green wavelength coverage that can coexist; And,, need the light of green and the red wavelength coverage that can coexist in order to observe interference of light phenomenon by G prism 110 and 130 reflections of R prism.
Fig. 2 is for representing the curve of light intensity according to wavelength, as shown in the figure, blue light is central distribution with 460nm, and green light is central distribution with 500nm, and red light is central distribution with 620nm.Blue light and green light within 460～500nm scope, especially within 470～490nm scope (first wavelength coverage: A) coexistence; Green light and red light within 500～620nm scope, especially within 540～580nm scope (second wavelength coverage: B) coexistence.
Therefore, in order to observe interference of light phenomenon, need the light filter (filter) that is used to extract corresponding to the light of a-quadrant by G prism 110 and 120 reflections of B prism; And,, need the light filter of the light that extracts the B zone in order to observe interference of light phenomenon by G prism 110 and 130 reflections of R prism.
Light quantity adjusting portion 30 is used to regulate the light quantity of selecting the light of light filter 20 extractions from wavelength.Because interference appears in the similar light of wavelength and amplitude easily, so light quantity adjusting portion 30 will be adjusted to certain amplitude by the similar light of wavelength coverage that wavelength select light filter 20 to extract, even its intensity is certain.Light quantity adjusting portion 30 be used to make the optical attenuator (optical attenuator) that the light quantity of outgoing reduces or be used for optical density filter (filtering) be the optical density optical filter of desired value (neutral densityfilter).
Optical collector 40 is used for concentrating by light quantity adjusting portion 30 regulates the light of intensity, and is delivered to prism unit 100.Optical collector 40 is preferably the convex lens that the light around being diffused into is collected.
Optical collector 40 has intrinsic focal length, and prism unit 100 preferably is positioned on the focus of optical collector 40.In other words, the focal length of optical collector 40 (f) preferably equates in fact with the distance of 110,120,130 exit facets from optical collector 40 to prism.Thus, can easily arrange prism unit 100, and by on the focal length (f) that prism unit 100 is placed optical collector 40, thereby collection efficiency improved.
Each clip 51,55 is used to support prism 120,130, and is connected in drive division 53,57 for prism 120,130 can be driven.Usually, clip 51,55 for simply, correctly governor motion Working position and preferably adopt anchor clamps (jig) as auxiliary body.
As mentioned above, the exit facet of each prism 110,120,130 has and is used for the incident light catoptron 111,121,131 of secondary reflection again.The prism unit 100 that contacts three prisms 110,120,130 has a limit and is about hexahedral volume about 10～15mm.Under the state of temporary fixed each prism 110,120,130, the transparent ultraviolet hardening resin of coating on each surface of contact.Hardened by ultraviolet ray in the ultraviolet hardening resin step that is completely fixed prism 120,130 afterwards.
Because 60 of light guide portion are used to change light path, thereby are not to be defined in prism, also can adopt catoptron, and come actively to change the position of prism or catoptron according to the position of display part 70.
The manufacture method and the light path of the optical devices that provide according to present embodiment are described with further reference to Fig. 4 below.
At first, each exit facet to prism 110,120,130 attaches catoptron 111,121,131 (S10).Catoptron 111,121,131 makes the light that incides prism unit 100 be reflected along incident path again.
Preferably coat bloomed coating (coating) material on the plane of incidence of the G prism 110 that is fixed, do not produce reflex so that incide the light of prism unit 100.
Secondly, the inscape of Fig. 1 is arranged in the precalculated position, so that arrange prism 110,120,130.
The white light that sends from white light source 10 selects light filter to be extracted as the first wavelength coverage (light (S30) of A:470～490nm) by first wavelength.
The light that is extracted is regulated its light quantity by light quantity adjusting portion 30, and is incided the plane of incidence of prism unit 100 after the light harvesting by optical collector 40.
Select the light that light filter extracted to comprise blueness and green by first wavelength.In the incident light, green light (I) is decomposed special film by the G color that is formed at G prism 110 and B prism 120 critical surfaces and to 110 internal reflections of G prism, and blue light (II) sees through towards B prism 120.Through the light (I) of G prism 110 inside by the catoptron 111 that is arranged at G prism 110 exit facets once more by same paths and from prism 100 unit outgoing.The green light (I) of institute's outgoing is shown in the display part 70 after taking through optical collector 40 and light guide portion 60 and by the CCD that is arranged at display part 70.
The blue light (II) of institute's incident divides degrading film by the B color that is formed at B prism 120 and R prism 130 critical surfaces and to 120 internal reflections of B prism, if comprise red light in the incident light, then sees through towards R prism 130.Through the light (II) of B prism 120 inside also by the catoptron 121 that is arranged at B prism 120 exit facets again by same paths and from prism 100 unit outgoing.The blue light (II) of institute's outgoing also is shown in the display part 70.
For correctly, reproduced image clearly, to make green light (I) and blue light (II) equal in length separately in principle through prism 120,130 inside.In the present embodiment in order within the error range of about ± 5 μ m, to make the optical range unanimity, thereby utilize white light with 3～4 μ m interference distances.Arrive the green light (I) and the blue light (II) of a certain position respectively through different paths, its phase change equals the poor of displacement, and forms the multiple interference fringe corresponding to variation phase.At this, the difference of displacement is equivalent to the poor of optical range.
Whether the image that the user observes display part 70 by mobile B prism 120 (S40) clear (S50).If it is clear that image becomes, then constructive interference takes place in explanation, and the difference that further specifies optical range is about 3～4 μ m.
If do not observe interference, then mobile once more B prism 120 and regulating, if observe interference, then fixedly the position of B prism 120 (S60).
Then, for the position of fixing R prism 130 and carry out said process repeatedly.That is, (light that B:540～580nm) extracts (S70) incides the plane of incidence of prism unit 100 through light quantity adjusting portion 30 and optical collector 40 with second wavelength coverage.
The incident light that incides prism unit 100 is green light (I) and red light (III), and green light (I) is reflected at the exit facet of G prism 110, and red light (III) is reflected at the exit facet of R prism 130.
Observe by mobile R prism 130 (S80) after the interference of green light (I) and red light (III), some phenomenons that relate to are shown in display part 70 (S90), then fixing R prism 130 (S100).
To prism unit 100 irradiation ultraviolet radiations ultraviolet hardening resin is hardened in the step of fixed prism 120,130.
At last, on each prism 110,120,130 of prism unit 100, attach CCD and finish the manufacturing (S110) of prism module.When attaching CCD, whether the image that is shown in display part 70 by judgement is synthesized is regulated.
The present invention is not to assemble this module by disposable step, but utilizes interferometer to assemble prism earlier in the process of the prism module that the assembling prism combines with CCD.Because the process need of the optical devices that assembling simultaneously is accurate, less has more energy and expense, therefore utilize interferometer in predetermined error range, to make optical range consistent in order to make improvements.
But the numerical value corresponding to error range and interference distance of the present invention can be changed according to the kind and the desired optical range of light source, thereby not limit claim scope of the present invention.
