title: Optical liquid-crystal-television correlator for particle-image-velocimetry processing.
abstract: An application of an inexpensive liquid-crystal television as a processor for full-field velocity measurement techniques that require two-dimensional correlation is presented. With the use of nonspecialized optics, the results compare well with digital correlations.
