Optical Real-Time Phase-Only Correlator Using Liquid Crystal Television
The spatial light modulator (SLM) is a key element in an optical processor. The principle limitations of the currently available SLMs are the limited phase and amplitude modulation capacity, the limited space bandwidth product (SBWP) and the limited speed. We use the commercial liquid crystal television (LCTV) as the SLM and build a real-time on-axis phase-only optical correlator. This approach allows the efficient use of the SBWP of the LCTV (200 x 200 and 440 x 480 for new type of LCTV) and provides high light efficiency.
