【摘要】： 本文阐述了合成全息技术的发展历程及我国的合成全息和模压全息技术现状,为了提高我国的合成全息技术,振兴模压全息行业,进行了真彩色动感立体模压全息技术的研究。 本文开展了两部分的研究工作:第一,提出一种新的一步合成真彩色动感立体全息图的技术。用三色光栅对彩色景物编码,4f光学系统进行彩色解码,并在光路中加上光栅进一步调制物光束,使用散射参考光,对景物的系列编码片做顺序记录,合成一张真彩色动感立体全息图。实验工作在重庆大学进行; 第二,为全息生产企业引进数字合成全息技术。将全息技术与数字技术相结合,采用新型空间光调制器----数字微反射镜器件(DMD),用计算机进行图形输入和处理,并控制一套自动记录系统做全息记录,制成真彩色动感立体模压全息图。相关实验在深圳大学反光材料厂进行。 结果表明:两种技术都能实现单色激光记录,白光再现,并且图像色彩真实,立体视觉强烈,有一定的动感效果。均可通过模压技术制成防伪力度高,艺术观赏性强的商标,也可应用于商业广告、产品展示、艺术装潢等领域。技术领先,应用前景广阔。 其中,一步合成真彩色动感立体全息技术记录过程十分简单,不需要三分色片,曝光次数大为减少;DMD数字合成全息系统实现了全息生产的自动化,图像输入实时化,解决了对位难题,取材空间更广阔,处理更方便。但前者的手工操作限制了该技术的产业化应用;后者的三狭缝编码合成真彩色原理使过程仍嫌繁琐,有庞大的曝光数目。 结合两种技术的DMD一步合成真彩色动感立体全息系统是可行的。如果将计算机与全息显示技术进一步结合,用数字彩色编码技术取代光学彩色编码方法,即可采用DMD数字合成全息系统一步合成真彩色动感立体全息。新的技术更领先,产品质量更好、更稳定,生产效率更高,劳动成本更低,将有更加广阔的应用前景。
[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.
