Optical image correlation using acoustooptic and charge-coupled devices

Not Accessible

Your library or personal account may give you access

Abstract

An optical processing method is presented which allows the correlation of two images to be computed in real time with a 1-D acoustooptic spatial light modulator as the input device. Two-dimensional processing is accomplished by a combination of spatial and temporal integration. The time-integrating processing is performed by a CCD detector that is operated as an optically addressed correlator.
