本文提出將小貓自泵相位共軛鏡應用在數位光學相位共軛器之建立與利用其來建構相位共軛時間微分器;藉由小貓自泵相位共軛鏡所具備之共軛訊號無像差及快速穩定等特性,我們得以建立高效能數位光學相位共軛器,與文獻上所提方法比較,其可克服各文獻方法之缺點;此外,結合電光調製器與小貓自泵相位共軛鏡,我們發展出一套相位共軛時間微分器,並將其用來做自追蹤,及在散射物體裡面產生聚焦訊號。 In this thesis, we propose a new method for the alignment of a digital optical phase conjugator (DOPC) and the design of a phase conjugate novelty filter based on the Kitty self-pumped phase conjugate mirror (Kitty-SPPCM). Kitty-SPPCM has advantages such like short response time and insensitivity to the environment. Our method of DOPC alignment includes all benefits for DOPC from various literature methods. Additionally, we design a phase conjugate novelty filter with Kitty-SPPCM and electro-optic modulator (EOM). In this research, we apply the phase conjugate novelty filter to do self-tracking and produce a focal point inside diffuse objects.
