Abstract

An optical real-time holographic autocorrelator for the processing of multiple exposure images in particle image displacement velocimetry is presented as a powerful alternative to conventional processing devices. This device is based on a Bi12SiO20 spatial light modulator and can result in processing rates as high as 100 frames per second. The limitations inherent to its operation are theoretically derived and some limits are given on the digital image processing algorithms used to analyze an autocorrelation pattern for deriving velocity information.
