Abstract:

This document discloses an optical correlator having a series of optical elements necessary for providing the comparison or correlation of incoming optical signals and for providing a readout beam representive of the correlation between the input signals and a detection system which is capable of rapidly and reliably detecting intensity peaks in the readout beam. These intensity peaks establish the actual correlation between the optical input signals. The detection system incorporates therein a pair of optical fibers, one of which having associated therewith means for effectively varying the length of that fiber. By varying the effective length of one of the fibers, an intensity detector can provide an output of the intensity peaks necessary in making the actual correlation determination between the optical input signals.
