Abstract

The purpose of this paper is to review a new direct construction of phase-only filters and to further document its potential use for threshold optical correlation detectors. This construction is a descendant of the constructions introduced in Kallman and leads to a significant improvement in signal-to-noise ratio (SNR) over previous methods. Simulations suggest that the resulting filters and their optimized binarizations can be designed to contain a great deal of information, to be stable under perturbations in the training set, to have a very low false alarm rate, and to be insensitive to large amounts of additive zero mean Gaussian or uniform noise.
