Abstract:	AR/MR新創公司Magic Leap利用體育館中鯨魚躍出水面的畫面成功募資20億美金，證實了人們心目中對 “無顯示器裸眼3D動態影像”的無限渴望。而本計畫所欲攻堅的領域是利用光學共軛投射技術，實實在在的逼近“無顯示器裸眼3D動態影像”。將這項技術發展到最後，所創造之3D動態影像將能夠使用任何牆面甚至家具作為螢幕，使得觀眾忽略掉螢幕之存在感，進而產生真實的“無顯示器裸眼3D動態影像”體驗感，並可避開雙眼立體影像技術難解的暈眩問題。現實中的數位光學共軛術面臨到空間光調製器的調製通道數遠小於散射面通道數的困境，使得共軛光在經由大面積散射面進行聚焦時產生了極大雜訊。因此我們將利用大面積的體積全像光學元件來產生光學共軛訊號，其可調製通道數將遠大於任何市面上SLM可調製之通道數，使的系統通道數只受限於光學系統所能容納的空間帶寬乘積。為了克服困難，我們將進一步開發獨特的牆面微結構以降低散射面通道數，並使其適合實施分時多功。本人在科技部前兩年的研究成果已經證實了我們所提方案之可行性，未來，這個計畫的成功執行將為觀眾帶來絕佳的觀賞體驗。 ;Magic Leap (an AR/MR startup) successfully raised $2 billion by using the video of a whale jumping out of the water in the stadium. It demonstrated the people's endless desire for "naked-eyes 3D vedio without display". This project uses "Digital-optical-phase-conjugation (DOPC) projector" to realistically approach "naked-eyes 3D vedio without display". By continuous development of this technology, the created 3D vedio will be able to use any wall or even furniture as a screen. It makes the viewer ignoring the presence of the screen and feel the "naked-eyes 3D vedio without display" as real. It can further avoid the difficulty of “dizzy feeling caused by accommodation vergence mismatch”faced by current stereoscopic-3D-image technology. However, current difficulty of this technology is the modulation channel-numbers of the "Digital-optical-phase-conjugate projection system" is much smaller than that of the scattering surface. It lead to severe noise when the phase conjugate signal is focusing through a large-area scattering surface. Therefore, we will use a large-area volume holographic optical element to generate an optical conjugate signal. The number of modulating channels will be much larger than the number of channels that can be modulated by any SLM on the market, so that the number of system channels is limited only by the optical system. The previous two-years research results of our project supported by the Ministry of Science and Technology have confirmed the proposed solution is absolutely feasible. In the future, the successful implementation of this project will bring excellent experiences to the viewers.
