Abstract

We use a commercially available liquid crystal television (LCTV) for encoding real-time on- axis continuous phase-only filter (POF) in a Vander Lugt type optical correlator. Theory and experiments show that the filter on the LCTV, that has phase mismatching and coupled amplitude modulation, retains a term, that is the true POF with a diffraction efficiency of about 70%, plus a zero order spot. The correlation output is a superposition of the POF correlation with an image of the input. The filter has advantages of on-axis POF correlation: high light efficiency and utilization of all the available space bandwidth product of the LCTV. Optical experimental results are shown.
