A time integrating acousto-optical correlator has been realized, which exploits a polarization discrimination technique based on a shear wave acousto-optical cell and permits to process the signal directly on the image plane. A CCD photodetector array displays in time the time-integrated signal developed in space, thus furnishing the correct correlation integral.

Abstract
A time integrating acousto-optical correlator has been realized, which exploits a polarization discrimination technique based on a shear wave acousto-optical cell and permits to process the signal directly on the image plane. A CCD photodetector array displays in time the time-integrated signal developed in space, thus furnishing the correct correlation integral. Preliminary results of autocorrelation functions are presented for single and double square pulses of 5 ?s duration. © 1981.File in questo prodotto:
