[Abstract]:In this paper, the development course of synthetic holography and the present situation of synthetic holography and moulded holography in China are described. In order to improve the synthetic holography technology in China and to revitalize the holographic industry of moulding pressure, the true color dynamic stereoscopic holography technology is studied. In this paper, two parts of research work are carried out: first, a new one-step synthesis technique of true color dynamic stereoscopic holograms is proposed. A three-color grating is used to encode the color scene, a 4f optical system is used to decode the color object, and a grating is added to the optical path to further modulate the beam. The series of coded pieces of the scene are recorded sequentially by using the scattering reference light. Synthesize a true color dynamic stereo hologram. The experiment was carried out at Chongqing University. Secondly, digital synthetic holography technology was introduced for holographic enterprises. In this paper, a new spatial light modulator, digital microreflector device (DMD), is used to input and process the graphics with a computer, and a set of automatic recording system is controlled to record holography by combining holographic technology with digital technology. The true color dynamic stereotype hologram is made. The experiment was carried out in the reflective material Factory of Shenzhen University. The results show that both techniques can realize monochromatic laser recording, white light reproduction, true color, strong stereoscopic vision and certain dynamic effect. It can also be used in commercial advertising, product display, art decoration and other fields. The technology is leading, the application prospect is broad. Among them, the recording process of one-step synthetic true color dynamic stereoscopic holography is very simple, there is no need for trichromatic film, and the number of exposures is greatly reduced. The DMD digital synthetic holography system realizes the automation of holographic production, real-time image input, solving the problem of alignment, wider material space and more convenient processing. However, the manual operation of the former limits the industrial application of the technology, while the principle of the three-slit coding and true color synthesis of the latter still makes the process cumbersome and has a large number of exposures. It is feasible to synthesize true color dynamic stereoscopic holography by DMD with two techniques. If the computer is further combined with the holographic display technology and the optical color coding method is replaced by the digital color coding technique, the true color dynamic stereoscopic holography can be synthesized by using the DMD digital synthesis holography system. The new technology is more advanced, the product quality is better, the stability, the production efficiency is higher, the labor cost is lower, will have the wider application prospect.
