摘要
An optical transfer function consisting of a phase-only term and an optimized passband is synthesized for constructing an incoherent optical correlator for recognition of a noisy gray-tone image. The proposed incoherent correlator can yield a sharp correlation peak with excellent noise tolerance. (C) 1995 Optical Society of America
