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.
