Abstract
The present invention relates to a kind of new image transmission device for transmission of optical image under natural light condition. It is composed of input holographic film H lambda (A,B) and out put holographic film H lambda (B,C) or three primary colours superimposed input holographic films HRGB (A,B) and three primary colours superimposed output holographic film HRGB (B,C) in pairs sticked separately on the incident window and outging window of the sufficient long transparent medium film (tape). Compared with optical fibre transmitted image beam, said invention intends to provide a kind of hologric image transmission tape featuring larger visual field, higher resolution, simpler technology and lower cost.
Description
A kind of novel biography that transmits optical image under the natural light condition that relates to resembles device-Achromatic holographic picture transmission tape.
Optical fiber resembles and each side such as optical communication is just obtaining increasingly extensive application and is listed in one of sign of current new technology revolution in biography.Optical fiber facsimile beam is many certain-lengths, superfine (approximately several μ to tens μ) optical fiber set bunchy, and the optical fiber at two ends will be by close relation arrangement one to one, and the two ends of light beam need to grind through solidifying.When image that tendency to develop is sent projected on the end face of optical fiber facsimile beam, this image promptly was divided into many picture dots by each root optical fiber on the bundle end face, and each optical fiber respectively will picture dot separately be sent to the other end of bundle and gathers imaging again.As seen the resolution of optical fiber facsimile beam is decided by the diameter of used optical fiber basically.In order to transmit a complete image, the bar number of the optical fiber that fiber optic image transmission is contained often reaches several ten thousand and even the hundreds of thousands bar.Resemble quality for guarantee passing, the grinding of being strict with the curing of two terminations of fibre bundle and end face is perfect as far as possible, and fracture of wire in the bundle and dark silk are reduced to bottom line, and technological requirement is very high.
The objective of the invention is to overcome above shortcoming, the Achromatic holographic picture transmission tape that the high visual field of a kind of resolution is big, technology is simple, cost is low is provided.
Basic structure of the present invention and principle, as shown in Figure 1.With wavelength is the coherent laser A of λ and the input hologram sheet H that B takes
λ(A, B) and be the output hologram sheet H that the coherent laser beam B of λ and C take with wavelength
λ(B, C) respectively with the optical cement sticker on relevant position with the transparent dielectric slab of optical surface (band) as shown in the figure, incident light A makes hologram sheet H
λ(A, B) diffraction goes out B light, as long as the angle of B optical propagation direction and dieelctric sheet optical surface is less than critical angle, as spread fiber, B light will be limited in propagating along dieelctric sheet in the dieelctric sheet because of total reflection constantly, up to being incident upon the hologram sheet H that is on the optimum position
λ(B C) makes it be converted into the C light that is beneficial to observation, i.e. outgoing picture information.Practice confirms that this holographic optics structure has biography and resembles function, and is achromatic under the natural light condition.But the C light of outgoing is general different with the A light color of incident, is bordering on monochrome (wavelength X) for obtaining to transmit the Achromatic holographic picture transmission tape of euchroic (even the A light of the C light of outgoing and incident is bordering on homochromy), can be with the input hologram sheet H among Fig. 1
λ(A is B) with output hologram sheet H
λ(B C), replaces with three primary colours hologram sheet stack part H respectively
RGB(A, B) and H
RGB(B, C) as shown in Figure 2.This part that superposes is as above-mentioned H
RGB(A B) is meant by the coherent laser A and the B that use three kinds of different wave length λ (red R, green G and blue B) respectively, three hologram sheet H that take the photograph under same light path
R(A, B), H
G(A, B) and H
B(A, B) the stack part that forms with the optics glue glued adhesion are referred to as to call three primary colours stack input hologram sheet H
RGB(A, B).
The present invention implements like this: paste admittedly with special input hologram sheet H with optical cement respectively on the input end (window) of the low-loss transmission transparent dielectric slab (band) with optical flat and output terminal (window) position
λ(A is B) with output hologram sheet H
λ(B C), constitutes non-euchroic Achromatic holographic picture transmission tape.Equally, with three primary colours stack input hologram sheet H
RGB(A is B) with three primary colours stack output chip H
RGB(B C) uses the optics glue glued adhesion on the input output window of transparent dielectric slab, can form the euchroic Achromatic holographic picture transmission tape.
Provide specific embodiments of the invention below in conjunction with accompanying drawing.
Fig. 1, non-euchroic Achromatic holographic picture transmission tape structure are cutd open and are shown and propagate the light path synoptic diagram.
Fig. 2, euchroic Achromatic holographic picture transmission tape structure are cutd open and are shown and propagate the light path synoptic diagram.
Fig. 3, lay transparent dielectric slab (band) structural representation of covering.
Wherein, 1 input hologram sheet H
λ(A, B), 2 output hologram sheet H
λ(B, C), 3 three primary colours stack input hologram sheet H
RGB(A, B), 4 three primary colours stack output hologram sheet H
RGB(B, C), 5 transparent dielectric slabs (band), 6 coverings.
As shown in Figure 1, will import hologram sheet H
λ(A, B) 1 and output hologram sheet H
λ(B, C) 2 usefulness optical cements are glued at respectively in pairs on the incident end (window) of the transmission transparent dielectric slab (band) 5 with optical flat and exit end (window) position and promptly form non-euchroic Achromatic holographic picture transmission tape, go out, incidence window can split both sides or homonymy at transparent dielectric slab (band) 5.
As shown in Figure 2, as another most preferred embodiment, will be by three primary colours stack input hologram sheet H
RGB(A, B) 3 and three primary colours stack output hologram sheet H
RGB(B C) 4 is glued at respectively on the incident end (window) of above-mentioned transmission transparent medium 5 and the exit end (window) and then forms the euchroic Achromatic holographic picture transmission tape.Promptly with three primary colours stack input hologram sheet H
RGB(A is B) with three primary colours stack output hologram sheet H
RGB(B C) replaces corresponding input hologram sheet H respectively
λ(A, B) 1 and output hologram sheet H
λ(B C) 2 gets final product.Above-mentioned input, be output on input that two right hologram sheets also can be glued at the both sides (as shown in Figure 1 and Figure 2) of transparent dielectric slab 5 or homonymy as required respectively, the output window (total reflection position).And transparent dielectric slab 5 can long enough, the flakiness band shape has certain flexibility, and its periphery is an air dielectric, because this picture transmission tape is to utilize inner continuous total reflection to propagate picture information as optical fiber, is clean and tidy so should guarantee the optical surface of above-mentioned transparent dielectric slab 5.Preferably as shown in Figure 3, lay the covering 6 of skim-low-refraction on the optical surface except that the window of coming in and going out of transparent dielectric slab 5, the suitable blacking in other side enters to prevent unhelpful internal reflection and parasitic light.Obviously must be the same to the material requirements of transparent dielectric slab 5 with making optical fiber, should be by low-loss material, make as transparent materials such as glass, quartz or plastics.Glass or plastics that its extramural cladding 6 is corresponding low-refractions.Not impaired and increase certain intensity for protection holographic picture transmission tape outside, also can be outside it coated one deck plastic protective sleeve.
In sum, advantage of the present invention is apparent. Not only technology is simple, and cost is low, and transmit resolution ratio height on the image quality, the visual field is big, is expected more superiorly than optical fiber facsimile beam, new technology, new unit as holographic optics have broad application prospects.
