本論文以小貓自泵相位共軛術為基礎應用於數位光學共軛系統,藉由Kitty-SPPCM之快速、穩定及大角度的容忍範圍等優點,建立出一套高效能的數位光學共軛系統。基於此數位光學相位共軛器設計出一套能重建光學資訊之三維實像投影系統。本文欲藉由費奈爾反射結構使系統有效通道數與共軛訊號效率提升。接著於模擬中探討多種系統參數對於共軛聚焦點之行為影響,於實驗中使用費奈爾反射結構並改善系統通道數量以及共軛訊號之表現。從實驗結果得知,我們成功地建立出一套三維實像投影之模型。;In this paper, the Kitty self-pumped phase conjugate mirror (Kitty-SPPCM) is applied to a digital optical phase conjugator (DOPC). The advantages of Kitty-SPPCM are fast, stable and with wide-angle tolerance. We apply the digital optical phase conjugator to a new-design 3-D real image projection system that can potentially scan 3-D points, which are originated from a fiber. To increase the effective channel numbers of the system, and the efficiency of the conjugate signal, we study to use a Fresnel reflective structure. In addition, we have developed a simulation model of the 3-D real image projection to analyze the conjugate -focal-point behavior for various system parameters. In the experiment, the channel numbers and the performance of conjugate signal have been observed enhanced by use of the Fresnel reflective structure. Then we have successfully demonstrated a useful model of 3-D real image projection.
