Paper Abstract

Optical filter is quite an important measure in optical information processing. In this paper, FIR (finite impulse response) filter theory is employed in optical filter design to set up a novel optical FIR filter model, based on the crystal birefringence effect. Using this model, arbitrary spectrum output can easily be obtained, including double channels. Here we present several optical FIR filter optimization approaches to get good performance and then give both spectrum and angle properties for this fiRer. Furthermore, we also present the experimental implementation and show G/M filter as an example, which has good application prospect in projection display field.
