Abstract

A compact configuration for a real-time updatable optical correlator is considered. The correlator is designed to operate with incoherent illumination and efficient phase filters, which can be implemented with real-time, updatable, electronically addressed, liquid-crystal spatial light modulator. In order to obtain both a rigid and a compact correlator, a configuration which can be incorporated with planar optics is investigated. The overall correlator includes two pairs of diffractive lenses, each for performing a Fourier transformation, one spatial light modulator and input and output interface devices. The design consideration and fundamental limits of a compact updatable correlator using off-axis, diffractive lenses are presented, along with some experimental results.
