Abstract

We describe a class of image-processing optical systems, based on a laser scanner, whose output is an electronic video signal from a simple photodetector. We show that certain image-processing properties of these systems are exactly equivalent to the properties of conventional, partially coherent, image-processing optical systems. These systems are of interest when we want to combine optical image processing with further electronic processing. Some applications, such as electronic read out of phase-encoded images, are discussed.
