Abstract : A high speed, high resolution, digital computer-based interrogation system for Particle Image Velocimetry has been developed. It utilizes advanced parallel array processing technology to achieve computational speeds comparable to those of current super-computers, and high resolution image acquisition equipment to achieve the data input rates necessary for high speed analysis of PIV images. Advanced cross-correlation techniques are incorporated into the algorithm which take advantage of the high speed capabilities and improve the quality of the measurements. The architecture, algorithms, and performance characteristics of the system are described. (Author)
