Description

Stereoscopic image device

The invention relates to a stereoscopic image device, in particular to an interference fringe generated by a light beam and a reference light wave, and the stripe is recorded on a film coated with a photosensitive material, so that the film can be reproduced by the reconstructed light source to reproduce the stereo image. The photographing device can realize the reconstructed image as a real image size or an enlarged image by changing the object light and light wave system when the stereo image is produced.

The most widely known stereoscopic image is the stereoscopic projection technology in Star Wars movies. With the development of modern technology, stereoscopic images can be presented through time-multiplexed or spatially multiplexed engineering techniques. The formation of a stereoscopic image needs to be projected into the two eyes through two two-dimensional images, and the angles of the two two-dimensional images cannot be changed too much, and a continuous stereoscopic feeling can be produced after being synthesized by the brain. However, the stereo illusion created by engineering technology has problems such as dizziness when the human eye is viewed, and the problem that people need to overcome due to engineering, so the stereoscopic image technology most suitable for human eyes is "hologram". The hologram can superimpose the reflected light waves on the object and record it on the photosensitive material to become a holographic display. After reconstruction, it can restore the multi-angle image of the object itself, in line with the needs and continuity of human eyes. Can overcome the problems of human factors engineering. If you want to increase the object display angle of the hologram, you need to read the image of the object 360 degrees and convert it into a 2D image, and then sequentially shoot the 2D image above the hologram. Form a circular trajectory. When the image is reconstructed, a light source can be placed above or below the holographic display. After the hologram is displayed, the previously recorded 2D image information is projected, and the plurality of 2D images can be superimposed into a continuous image information. Received by the human eye and form a stereoscopic image in the brain's vision.

However, the conventional holographic display film shooting system, in order to present more complex images, the more components of the shooting system, the more complex the system, the most difficult to improve is the need for a large area of space to erect the system, mainly It is because the conventionally used light source is a gas laser light generator, and the length is often more than one meter, because the length of the longer laser cavity can have better optical interference effect. With the advancement of optical science, it is only necessary to generate a laser light source with good interference through a ring-shaped glass optical waveguide, and the glass optical waveguide has flexibility, and can effectively reduce the shooting system of the holographic display film, and By reducing the number of system components, a holographic system that does not require the use of mirror elements has been developed.

On the other hand, since the continuous image of the hologram display film is recorded as a ring type, a three-hundred and sixty-degree stereo image can be generated after reconstruction, but the size of the image is limited by the width of the recorded ring shape, so the present invention also The improvement of the object light and light wave system is proposed, and a stereoscopic image with a magnifying effect is developed.

Reflective imaging panels are used on the object light system, unlike the transmissive imaging panels used in conventional holographic systems, because reflective imaging panels can effectively reduce the optical path. Therefore, the present invention can achieve the purpose of system miniaturization. The invention also proposes that after the imaging lens of the object light system is removed, the enlarged image can be projected on the negative film to form interference fringes with the reference light source, and the enlarged stereoscopic image effect can be obtained after reconstruction.

The following is a specific example to illustrate the implementation of the "stereoscopic imaging device" disclosed in the present invention, and those skilled in the art can understand the advantages and effects of the present invention by the contents disclosed in the specification. The present invention may be carried out or applied in various other specific embodiments, and various modifications and changes can be made without departing from the spirit and scope of the invention. In addition, the drawings of the present invention are merely illustrative and are not intended to be construed in terms of actual dimensions. The following embodiments will further explain the related technical content of the present invention, but the disclosure is not intended to limit the technical scope of the present invention.

It will be understood that, although the terms first, second, third, etc. may be used herein to describe various elements or signals, etc., these elements or signals are not limited by these terms. These terms are used to distinguish one element from another, or a signal and another. Also, as used herein, the term "or" may include all combinations of any one or more of the associated listed items.

FIG. 1 is a schematic diagram of an imaging system of a stereoscopic image device according to a preferred embodiment of the present invention. As shown in FIG. 1 , it includes a light emitting unit 1 , wherein the light emitting unit 1 is a light source generator. A beam of light is produced. For example, the light emitting unit 1 can be a laser light source emitter (for example, a glass waveguide type laser light source generator) to generate a laser beam, and the laser beam generating structure is a glass waveguide type, and the laser beam The wavelength range of the light source emitted by the light beam includes invisible light and visible light, and the invisible light may be ultraviolet light or infrared light, for example, and the visible light may be blue light, green light, orange light or red light. Further, when the light-emitting unit 1 is a glass waveguide type laser light source generator, its volume can be much smaller than that of a conventional large-area laser generator.

In the above, the light beam emitted by the light-emitting unit 1 can pass through a light transmission unit 3 for transmitting the light beam generated by the light-emitting unit 1, and the light beam is transmitted or propagated through the light transmission unit 3 and then enters a light splitting unit 4, and the light beam can be The light is transmitted into a light transmission waveguide 31 and a reference light transmission waveguide 32. For example, the optical transmission unit 3, the object optical transmission waveguide 31, and the reference optical transmission waveguide 32 can be a glass waveguide and can propagate the light beam within the glass waveguide. At the same time, since the optical transmission unit 3, the object optical transmission waveguide 31, and the reference optical transmission waveguide 32 are all flexible waveguides, they can be arbitrarily moved or curled.

Next, the polarization unit 2 can cooperate with the optical transmission unit 3, the object optical transmission waveguide 31, and the reference optical transmission waveguide 32 to maintain or control the light beam of the light beam in the optical transmission unit 3, the reference optical transmission waveguide 32, and the object optical transmission waveguide 31. The polarization direction (or polarization direction) is such that after the light beam is emitted from the object light transmission waveguide 31 and the reference light transmission waveguide 32, good interference fringes can be generated and recorded on the film unit 8. For example, in the embodiment of FIG. 1, there may be three polarization units 2, and the light beam may pass through one of the three polarization units 2 and then enter the beam splitting unit 4, and the beam passes through the beam splitting. The unit 4 is incident on the object optical transmission waveguide 31 and a reference optical transmission waveguide 32. That is, a part of the light beam can be projected into the reference light transmission waveguide 32, and another part of the light beam can be projected into the object light transmission waveguide 31. According to the above, a part of the light beam is emitted from the reference light transmission waveguide 32 and passes through a waveguide unit 5, and After forming a reference beam 41, it is directly irradiated onto a negative film 81 of the film unit 8. For example, the composition of the wave expanding unit 5 may be a small magnifying lens capable of expanding light waves. Further, for example, the polarization unit 2 may be disposed on the path of the reference optical transmission waveguide 32 to maintain the polarization direction of the light beam. Thereby, a part of the light beam can be emitted from the reference light transmission waveguide 32 and the polarization unit 2, and then projected onto the substrate 81 through the waveguide unit 5. It is to be noted that the center position of the wave expanding unit 5 may overlap with the center position of the film 81.

According to the above, another part of the light beam is emitted from the object light transmission waveguide 31, and passes through a waveguide unit 5 to form an object light beam 42 and then enters a projection unit 6. For example, the polarization unit 2 may be disposed on the path of the object optical transmission waveguide 31 to maintain the polarization direction of the beam. Thereby, another part of the light beam can be emitted from the object light transmission waveguide 31 and the polarization unit 2, and then projected onto the projection unit 6 via the waveguide unit 5. Further, the projection unit 6 can be matched with an information unit 7. At the same time, the projection unit 6 can include a convergence lens 61, a beam splitter 62 and a magnifying lens 63. The information unit 7 can include a display panel 72 and a computer 71, which mainly inputs a two-dimensional image into the projection unit 6, and finally images the two-dimensional image on the negative film 81. Thereby, after the object light beam 42 is transmitted through the convergence lens 61, it can become a convergent object light beam, and the converged object light beam is incident on a beam splitter 62, and then the object light beam 42 is reflected to the display via the beam splitter 62. Like the board 72. In addition, the computer 71 can input an image information to the display panel 72, and then the reflected object light beam 42 passes through the beam splitter 62, and the 2D image information of the display panel 72 is taken out and converged into a focus. A magnifying lens 63 is centered. Further, the manner in which the projection unit 6 and the information unit 7 are matched with each other can be provided by the computer 71 through the information unit 7 to the reflective display panel 72, and then the light is projected on the reflection mirror 62 in the projection unit 6. After the image board 72 is placed, the information of the image is guided.

That is, the display panel 72 can reflect a two-dimensional image to the convergent object beam and once again pass through the beam splitter 62, and the two-dimensional image is converged into a focus at the center of the magnifying lens, and the two-dimensional image is projected on On the film unit 8. Also, for example, The film unit 8 can include a negative film 81 and a rotating shaft 82. The negative film 81 can record an optical image, and the negative film 81 can be placed above the rotating shaft 82 to enable the rotating shaft 82 to rotate the negative film 81. Meanwhile, the projection unit 6 can project an enlarged image to On the film 81. Thereby, the reference beam 41 and the object beam 42 can be simultaneously projected at the same position on the film 81, and an interference fringe 92 (refer to FIG. 2) is formed to record the two-dimensional image on the film 81.

In the above, that is, after the two-dimensional image of the magnifying lens 63 becomes a divergent light 422, it can be directly irradiated onto the negative film 81. The divergent light 422 forms an interference fringe 92 (see FIG. 2) with the reference beam 41, and records the image on the display panel 72 on the negative 81. In addition, for example, the display panel 72 in the information unit 7 can be a reflective display panel 72. The reflective display panel 72 provides an image information by means of a reflected light source. Then, when the image of the display panel 72 is recorded once by the interference fringe 92, the computer 71 transmits a signal to the rotating shaft 82 to control the rotating shaft 82 to rotate by an angle, and then the computer 71 inputs another image to the image. The board 72, and then the divergent light 422 and the reference beam 41, record the interference fringes 92 on the backsheet 81. Similarly, the computer 71 will control the rotation of the shaft 82 by an angle until all images have been recorded. Therefore, when all of the two-dimensional images are taken, a ring-shaped interference fringe pattern is formed on the film 81. In other words, the rotating shaft 82 of the film unit 8 can be connected to the computer 71 to operate in synchronization with the input of the two-dimensional image. At the same time, the computer 71 sequentially inputs the two-dimensional image to the display panel 72, and after inputting a two-dimensional image (illuminated on the negative film 81), the rotating shaft 82 is rotated once, so that each of the two-dimensional images and the last-irradiated two-dimensional image Overlapping, a ring-shaped interference fringe is finally formed on the backsheet 81.

Next, the film 81 is subjected to a standard rinsing process, developed and fixed to form a display film 93. In other words, together with the embodiment shown in FIG. 2, the negative film 81 having the annular interference fringes 92 can be turned into a display unit 9 under the light, including a reconstructed light source 91 and a display negative film 93. An interference fringe 92, a convergent diffracted light 94, and a stereoscopic image. In the embodiment of Figure 1, the stereo image Can be adjusted to enlarge the size of the stereo image.

A stereo image. For example, in the embodiment of FIG. 1, the imaging unit 6 does not include an imaging lens. Therefore, after the interference fringe 92 on the negative film 93 is irradiated by the reconstructed light source 91, a divergent diffracted light 96 can be generated and formed. A real magnified stereo image 97 (or may be referred to as an enlarged stereoscopic image).

Next, referring to FIG. 3, it can be seen from the comparison between FIG. 3 and FIG. 1 that an imaging lens 64 is further incorporated in the projection unit 6 of FIG. 3, which functions to reduce and image the two-dimensional image passing through the magnifying lens 63. On the backsheet 81. That is, when the object light beam 42 forms a focus at the center of the magnifying lens 63, the converged image can be projected onto the film 81 via the imaging lens 64.

As described above, referring to FIG. 4, if the function of the imaging lens 64 in FIG. 3 is used, in the display unit 9, when the interference fringe 92 on the negative film 93 is illuminated by the reconstructed light source 91, convergent diffracted light is generated. 94. Finally, a real-size stereoscopic image 95 is formed. It should be noted that other components in FIG. 3 are similar to those in FIG. 1 described above, and are not described herein again. In addition, in the embodiment of FIG. 3, the projection unit 6 projects the image on the developing panel 72 to the negative film 81 through the imaging lens 64, and it is also possible to The imaging lens 64 is removed so that the two-dimensional image becomes an enlarged image and is projected onto the film 81. Therefore, the imaging lens 64 can change the final reconstructed holographic image in the present invention to be an actual image size or an enlarged image.

Next, referring to FIG. 5, FIG. 5 is a mirrorless system of the present invention, and the non-imaging lens can form another stereoscopic image system of enlarged size. As can be seen from the comparison between FIG. 5 and FIG. 1, the greatest difference between the embodiment of FIG. 5 and FIG. 1 is that in the embodiment of FIG. 5, only one polarization unit 2 can be provided, and two waveguide units 5 are not provided. In addition, the embodiment shown in FIG. 5 is similar to the embodiment of FIG. 1 and FIG. 2 described above, and details are not described herein again. It should be noted that, in the embodiment of FIG. 5, the waveguide unit 5 may not be provided, and the beam may be emitted from the object light transmission waveguide 31 and the reference light transmission waveguide 32, and the waveguide itself has a high numerical aperture value. When the light is emitted, it will automatically expand the light into a divergent wave.

When the light is emitted, it will automatically expand the light into a divergent wave.

The present invention is different from the conventional holographic display production system. The present invention proposes five novel concepts, one of which is to use a glass waveguide type light source system to generate a laser light source, and the other is to use a glass waveguide to transmit a laser. The light source, the third is to use a reflective display panel, which can reduce the distance of the entire optical path by the principle of reflection. The fourth is to use the divergent light image to project on the film. The fifth is that the whole holographic display production system does not need to use the reflective surface. The mirror controls the direction in which the laser beam travels because the glass waveguide has flexible characteristics and can be moved and curled arbitrarily. Therefore, the reflective display panel, the glass waveguide laser, and the glass waveguide are used to transmit the laser energy. The size of the entire production system is reduced, even the entire system is reduced to the size of a shoe box; and the conventional holographic display production system requires the use of multiple reflective mirrors, which require the use of a large volume of gas laser to emit a laser source and penetrate The type of image board makes the entire optical system too long, so it is impossible to make the volume small and it is difficult to promote the system to the market.

Therefore, the present invention is a novelty and progressiveness that can be used by the industry, and should meet the requirements of the patent application of the patent law of China. Please, pray that the Bureau will grant the patent as soon as possible. However, the above-mentioned embodiments are not intended to limit the scope of the invention, and the equivalents and modifications of the shapes, structures, features and spirits described in the claims of the present invention should be included in the patent application of the present invention.
