【摘要】： 本文闡述了合成全息技術的發(fā)展歷程及我國的合成全息和模壓全息技術現(xiàn)狀,為了提高我國的合成全息技術,振興模壓全息行業(yè),進行了真彩色動感立體模壓全息技術的研究。 本文開展了兩部分的研究工作:第一,提出一種新的一步合成真彩色動感立體全息圖的技術。用三色光柵對彩色景物編碼,4f光學系統(tǒng)進行彩色解碼,并在光路中加上光柵進一步調制物光束,使用散射參考光,對景物的系列編碼片做順序記錄,合成一張真彩色動感立體全息圖。實驗工作在重慶大學進行; 第二,為全息生產企業(yè)引進數(shù)字合成全息技術。將全息技術與數(shù)字技術相結合,采用新型空間光調制器----數(shù)字微反射鏡器件(DMD),用計算機進行圖形輸入和處理,并控制一套自動記錄系統(tǒng)做全息記錄,制成真彩色動感立體模壓全息圖。相關實驗在深圳大學反光材料廠進行。 結果表明:兩種技術都能實現(xiàn)單色激光記錄,白光再現(xiàn),并且圖像色彩真實,立體視覺強烈,有一定的動感效果。均可通過模壓技術制成防偽力度高,藝術觀賞性強的商標,也可應用于商業(yè)廣告、產品展示、藝術裝潢等領域。技術領先,應用前景廣闊。 其中,一步合成真彩色動感立體全息技術記錄過程十分簡單,不需要三分色片,曝光次數(shù)大為減少;DMD數(shù)字合成全息系統(tǒng)實現(xiàn)了全息生產的自動化,圖像輸入實時化,解決了對位難題,取材空間更廣闊,處理更方便。但前者的手工操作限制了該技術的產業(yè)化應用;后者的三狹縫編碼合成真彩色原理使過程仍嫌繁瑣,有龐大的曝光數(shù)目。 結合兩種技術的DMD一步合成真彩色動感立體全息系統(tǒng)是可行的。如果將計算機與全息顯示技術進一步結合,用數(shù)字彩色編碼技術取代光學彩色編碼方法,即可采用DMD數(shù)字合成全息系統(tǒng)一步合成真彩色動感立體全息。新的技術更領先,產品質量更好、更穩(wěn)定,生產效率更高,勞動成本更低,將有更加廣闊的應用前景。
[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.
