Abstract

Three types of time-integrating acousto optical correlator with delay time increasing have been designed developed and investigated. They based upon: 1) registration photoreceiver array is placed in lens focal plane; 2) diffracted optical bemas are separated by optical elements placed in a focal region; 3) photoreceiver array is placed in a plane situated between focal and image planes. The main idea of them is dividing the long signal into some portions and changed the carrier frequencies for every portion in order to prolongate the correlation process.
