Paper Abstract

An optical processor for generating a two-dimensional squared autocorrelation function is presented for post processing Particle Image Velocimetry (PIV) photographs of fluid flows. The incoherent-to-coherent conversion is performed by an optically addressed spatial light modulator. The optical processor presents a fast and comparable alternative to the numerical processors, which typically are used for this purpose. Results of analysis of synthetic tests and real fluid flow PIV images are present.
