Paper Abstract

A two-dimensional system model, including the birefringent low-pass filter (BLF), was designed and a cost function was formulated. This model takes optical system into account in designing BLF. Optimization of the parameter of BLF is acquired by this new method. Best performance of BLF is realized when distance d of o light and e light is about half size of a pixel. Moreover, the relation between the optimized distance d and the cutoff frequency of ideal optical system was established. It is proved that the optimized distance d becomes smaller when the cutoff frequency of optical system increases.
