The film is either a full-length film and so on. Although the following figures are specific holographic synthesis systems, this is only used to illustrate the technology in this case and is not intended to limit the scope of application of this case. 7 The reference light angle referred to in the following case refers to the angle between the reference light and the normal of the film. When the film is a flat surface, the normal line is a single 'but when the film is plum-shaped or conical, the normal line has a complex However, this is the definition of the angle between the light and the _ surface. In this case, the reference light angle is a fixed angle. 3 is a schematic diagram of a system according to the embodiment of the present invention. Referring to FIG. 3, the holographic image synthesis system 2 includes a light emitting unit 10, a light splitting unit 12, a reference light unit 14, an image generating unit 16, an object light unit 18, and The film is 2 inches. The illuminating unit it 10 is used to provide the _beam 1 〇1, which can provide the same beam, such as various laser emitters, wherein the laser can be a gas laser (such as a nipple laser) if viewed from a medium, Carbon dioxide laser, liquid laser, _laser or semi-laser. Further, in terms of wavelength, it may be a visible light or an invisible light laser. The light single/〇12 receives the coherent light beam 1〇1 provided by the light emitting unit 1〇, and divides the same light adjustment light 1 〇1 into a reference light beam 121 and an object light beam 12: the light splitting unit 12 may include a light beam A separation mirror (Beam Splitter, BS) 122, and a plurality of optical components, for example, the mirror 124 is disposed at an appropriate position to guide the coherent beam 1〇1, and the function thereof is to divide the coherent beam into the reference beam 121 and the object beam 123. . The reference light unit 14 receives the reference beam 121 of the beam splitting unit 12, and outputs a reference light wave 141 based on the reference beam 121. In an embodiment, the reference light unit μ may be a spatial filter (SF) 142 to remove spatial noise for the reference light, and the spoon is dry, for example, by a confocal convex lens group and a pinhole. Composition, but this case is not limited to this. The reference light unit 14 may also include other optical elements to direct or optimize the reference beam 121 to rotate a reference light wave 141' including, for example, a mirror 146, a focal length unequal M437477** mirror 144, and the like. The reference illuminant 14 can also include dimmable components, such as materials that modulate amplitude, her filaments. The reference light unit 14 processes the reference beam (2) and outputs the reference light wave 141, and adjusts the angle at which the reference light wave 141 is incident on the film 2〇 such that the reference light wave 141 enters the film 2〇 at a reference light angle. The image generating unit 16 provides at least the age of the needle, and the image may be a single-angle image of the recorded object 162 or a multi-angle multi-mirror. Second, the target object 162 can be monochrome or multi-colored or have grayscale. In the embodiment, the image generating unit 16 includes an image sensing element 164, an image processing electronic device 166, and a display 168. The image capturing component 164, such as a CCD camera, captures a single-angle image of a target object 162 or a plurality of images of multiple angles, wherein the image capturing component 164 or the target object 162 can be moved and adjusted to capture the desired angle. Image. The electronic device 166, e.g., a computer, which can process the image, receives the image 161 from the image sensor 164 and performs image processing. Referring to Fig. 4, in the case where the jersey image includes images of different angles of φ 贞, each image has the same two-dimensional pixel array (captured pixels) after being captured. In this case, the method of reducing the pixels of the image is adopted to reduce the number of times the film is repeatedly exposed in the future, for example, the image grapefruit is separated from the pixel. For example, the image capturing device captures the front and back three images of the target object 162 with a setting of the pasting pixel 10*10, and each frame of the image is subjected to image extraction processing to become the image frame 63. According to the imaging sequence, the image 163 is the first image. When the framed image 1631 is processed, only the projection pixels 16311 and 16312 are retained. When the image 163 is the second frame processed image 1632, only the projection pixels 16321'16322 are retained; when the image 163 is the third frame processed image 1633 Only the projected pixels 16331, 16332 are retained. The projection pixels 16311, 16312, 16321, 9 16322, 16331, 16332 are complementary image information to construct a complete multi-view image of the target object 162. Therefore, the pixel value of the projected pixel after image 163 (1631, 1632, 1633) is less than the pixel value of the captured pixel, but each (four) image has a full profile of the target object 162. In the case of 'this case', the number of pixels is reduced and the complementary image information is taken into account. The number of projection pixels that must be retained for each frame of image is visually designed. According to the above-mentioned 'actually--the aspect' image processing, the pixel processing will not cause the inconsistency of the reconstructed image. On the other hand, each pixel image is reduced in pixels, which can reduce the weight of the subsequent film. The number of times, so m made a (four) unified photo film due to the number of exposures can not show the consequences or the size is too small and the brightness is not enough. Next, the 'visual H 168 ', for example, a liquid crystal screen, can display the image 163 processed by the electronic device 166 that can process the image. The image 163 can be an image of the image pomelo before and after the different viewing angles, or the color separation process. - a monochrome component image, a second monochromatic component image, and a third monochromatic component image. The object light unit 18 then directs the object light beam 123 from the beam splitting unit 12 to the image generating unit 16 to generate an object light wave 181. In the present hand, the subtracting unit 18 includes a plurality of optical elements, such as, but not limited to, a lens group 182 or a mirror 184 that directs the object light beam 123 to the imager 168 of the image generating unit 16 to output an image into the object light. Light wave 181. Referring to the circle 5, on the film 20, the object light wave 181 corresponding to the image 1631 is incident on the film. The region where the reference light wave 141 interferes is the exposure interference region 16311, 163 21 y, /, the medium exposure interference region 16311, which is a projection projection pixel.

Since the object light wave 181 is processed by the image pomelo, the area outside the exposure area is not exposed when the image is recorded finely. Similarly, in addition to the image processing method, the object light unit 18 in the present case may further include a semi-cylindrical mirror disposed on the object light wave 181 person before the film 2 。. The reference light wave 141 and the object light wave 181 are incident on the negative film 2 to form a plurality of interference fringes on the negative film 2', wherein the wire wave wave 181 passes through the circular (four) composite hologram conventionally known by the semi-cylindrical lens. The optical imaging system includes a cylindrical lens, but the negative film is placed on the good surface of the object light, so the _ effect is bad. The imaging surface disk omnidirectional system removes the cylindrical lens and images the object. In the case of repeated exposure, the number of repeated exposures of such a film on the photographic surface of the hologram is still excessively doubtful. Referring to Fig. 6', the object light unit 18 of the present invention includes a half cylindrical mirror 186 and a matching lens group 182 to form a suitable object light imaging system, i.e., the focal plane is located at an appropriate distance from the center of the semi-cylindrical mirror 186. It is denoted by d1, but the negative film 2〇 of the present case is not disposed on the focal plane distance d1 of the objective light imaging system to cause interference. The film 2 of the present case is disposed at a position close to the focal plane of a defocusing distance d2 or d3, and can also be referred to as a depth of field range (between d2 and d3) of the object photoimaging system. When the negative film 20 11 M437477 is set at this defocus distance, the interference fringes formed by the object light wave and the reference light wave can still reconstruct a holographic image recognizable by the human eye. Referring to Fig. 7', the object light unit of the present invention adopts a semi-cylindrical mirror 186 and a matched lens group m2 to form an appropriate objective light imaging system 'when the negative film 20 is placed in the depth of field range of the objective optical imaging system but does not include the focal plane. Above the distance, the areas exposed on the film are the exposure interference regions 163a' 163b, respectively. It is to be noted that the 'exposure interference region i63a, which is a first image and a second image of different angles of view of the target object, may be subjected to the aforementioned image pomelo processing or not subjected to image extraction processing. However, after the objective optical imaging system is formed by the semi-cylindrical mirror 186 and the matched lens group 182 of the present invention, the exposure interference regions 163a, 163b of the incident light waves incident on the negative film 2 are smaller than those of the semi-cylindrical or cylindrical lens. The conventional system can reduce the number of times the film is repeatedly exposed, thereby obtaining a key image with a relatively brighter brightness. In addition to reducing; ^ is the number of times of light, the case is better than the conventional system's is to set the film in the depth of field range, can eliminate the fence effect, so that the interference fringes recorded on the film can be clear and eye-catching image. It should be noted that the setting of the semi-cylindrical mirror in this case or the way of image extraction, white can reduce the number of repeated exposures of the negative film, and for a single-aged image, the image with a small number of Pa can be used for the semi-cylindrical mirror. The setting of 186 or the way of image extraction, for multiple images, can be applied to the system at the same time to obtain a bright and clear reconstructed image. Under the advantage of the image-extraction processing image and the semi-cylindrical mirror to reduce the repeated exposure of the film, 'even the simple image can be recorded on a specific position on the film 2Q, for example, when the film a & the film' is recorded in a specific (four) fresh On the path, the image of other target objects can be included on different radii 12 M437477. When the image is viewed, the target image recorded by different tracks can be observed, so that the image of the orbit can be generated, that is, the reconstructed image is more The change makes the reconstruction of the image, for example, the traditional shooting and the production of the full photo, because the consideration of the bottom into a diffraction effect is not good, so it can only make a full image of the object of 4 s, but the application The 4th handle is away from the pixel, reducing the repeated exposure of the film: the object is made of multi-channel _tl:channe丨) and the shadow has a dynamic silk (four) image. The image is imaged by the image of the second embodiment. For example, the observer can be 15 to 45 = the system diagram of the second embodiment of the present invention. The composite system image processing for the color object 162' holographic image may include color separation processing of the image 161 to separate each color image in the image from the symplectic image into the image 161 - the first monochromatic component image and a first Two monochromatic components like, 1 . . " 第 — - a first monochromatic image of the early color component image is different from the second monochromatic component image - the second single morning bar, for example, divides the image into two, two-dimensional images of red, green and blue It is an early color component image, a two-color component image, and a third monochrome component image. For a color target object, the object 18 may further include an angle adjusting component 188, such as an _-乂 反射 mirror adjusted with a driving module, to adjust the angle at which the object light wave 181 is incident on the film 20. For example, the first monochromatic component image and the second monochromatic component image are respectively red component images, and the green component blade image 4 ′ is used to adjust the angle at which the object light beam 181 is incident on the film 20 . Let the _ should be red component image light wave 13 M437477 • · 181 and Cangkook light wave 141 with the __ first-degree, the angle between the object light wave 181 corresponding to the green component image and the reference light wave 141 is a second clamping angle; similarly, the angle between the object light wave 181 corresponding to the light-intensifying component image and the reference light wave 14彳 is a third clamping angle, wherein the angle of the reference light wave 141 entering the negative film 2〇 does not change, Therefore, the adjusted object is the object light wave 181 corresponding to the different color light component images, and the exposure areas corresponding to the three color component images incident on the film 20 may be the same 'partially overlapping or not overlapping.光学Because of the adjustment of the optical system of holographic imaging, it is difficult to reconstruct one of the optical components once it is fixed. It is quite time-consuming to reconstruct the optical path. In this case, before the incident light wave enters the negative film, the angle of incidence of the object light is adjusted by the angle adjusting component 188. The advantage of this type of adjustment is that the imaging optics can remain fixed, reducing the time required to reconstruct the optical path. Furthermore, according to the above, the angle between the different monochromatic component images and the reference light wave of the fixed incident angle is changed, and the object light wave and the reference light wave are incident on the film to form interference fringes, and when the image of the target object is reconstructed by the film, the reference light source is used. Fixed, the reconstructed image presented exhibits a color effect. 9 is a schematic diagram of a system according to a third embodiment of the present invention, which differs from the first embodiment in that the reference light unit 14 of the holographic image synthesis system 6 further includes an image generator 148 ′ via the reference beam 121. The optical element 彳46' guides the eight-shot image generator 148 to form a reference light wave 141 with target image information, so that the reference light wave 141 corresponding to the area outside the target image is incident on the negative film 20, thereby reducing unnecessary The generation of interference fringes and the number of repeated exposures. Although the present case is described by the above embodiments, the form and details of the design can be changed without being deviated from the creative spirit of the case. It will be understood by those skilled in the art that the preferred embodiment of the present invention is only a mode of 14 M437477 which can be embodied by the principle of the present invention, but is not limited thereto, and should be applied for patents attached thereto.
