Abstract

The system consists of two mutually orthogonal linearly polarized laser beams carrying the Fourier spectra of a reference pattern and an input pattern into a photorefractive crystal, respectively. The image of every reference pattern in the input would appear at the output plane regardless of whether it is moving or not. However, a still non-reference pattern presented at the input plane would not show up at the output plane. Therefore stationary noise pattern never shows up in the output plane.
