碩士 === 國立中央大學 === 光電科學與工程學系 === 106 === 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.
