| dc.description.abstract | 本論文利用透鏡陣列 (lens array) 做為數位光學相位共軛 (digital optical phase conjugator, DOPC) 投影系統的屏幕，利用DOPC重建訊號光的能力與透鏡陣列在空間中重建出大可視角度 (angle of view) 與 Eyebox 的 3D 立體實像。在此系統中利用 SLM 調製相位的能力，藉由補償不同階數的像差提高成像的峰值與背景雜訊比 (peak to background ratio，PBR)。接著比較利用單一透鏡作為屏幕與利用透鏡陣列作為屏幕，兩者之間的Eyebox大小。最後我們藉由調製重建物光資訊在SLM上XY軸的傾斜 (tilt) ，使原本的重建訊號光位置產生位移，並在SLM上將多張重建物光資訊的相位圖疊加，使我們可以利用此系統重建出英文字母投影至空間中。 | zh_TW |
| dc.description.abstract | In this thesis, we use the lens-array as the screen of the Digital Optical Phase Conjugator (DOPC) system. By using the ability of DOPC system with the lens-array, we can reconstruct a three-dimensional image with large field of view (FOV) and Eyebox. Since the Spatial Light Modulator (SLM) has the ability to modulate phase, we compensate different modes of the orthonormal rectangular polynomials to raise the peak to background ratio (PBR) of the reconstructed point. Then, we compare the difference of the reconstructed image’s Eyebox between using single lens as the screen with using lens-array as the screen. At last, we modulate the tilt of the X and Y axis on the SLM of the phase of the reconstructed signal light. The reconstructed point will move to different position. By superimposing two or more phases to one picture on the SLM, we can finally reconstruct a latter to the space by using one point. | en_US |
