Abstract
An incoherent optical processor that highlights the dynamic parts of a n image is proposed. A direct image is added up with the contrast reve rsed one provided by a photorefractive crystal and an arrangement of p olarizers. The crystal finite response time gives a temporal shift bet ween the superposed images. Experimental results related with a travel rectangle function are analyzed.
