Abstract

Direct double pulsed image recording onto a bistable optically addressed spatial light modulator (BOASLM) results in easy and fast data acquisition for particle image velocimetry (PIV). In combination with the parallel optical spatial autocorrelator based on another BOASLM for PIV data processing, a fluid flow map can be obtained within seconds without the necessity for off-line processing. In this paper the feasibility of recording double pulsed particle images is explored and demonstrated experimentally.
