1 November 1991 Real-time nonlinear optical correlator in speckle metrology
Author Affiliations +
In speckle correlation technique, both the specklegram and its Fourier transformed fringe pattern are detected by nonlinear Optic RAM detectors. The speckle correlation is calculated by the nonlinear optical correlator using a phase modulation property of a liquid crystal television. The effects of the binarization for the signals on the diffraction efficiency are discussed theoretically and experimentally.
