Particle Image Velocimetry is now a well established technique for the instantaneous measurement of unsteady flow. However, two major limitations of the technique are the error suffered due to out-of-plane motion, and the use of time-consuming variable photographic processes to record the image. These limitations can be overcome by the measurement of the velocity components in all three dimensions and the use of solid state technology to record the image. The application shown in this paper, employed two CCD cameras connected to a PC- based imaging system, to record 3D PIV information. The major problems encountered were mainly related to the range required to image the region of interest (1.80 meters from the tunnel viewing window) and the synchronization and matching of the cameras; both in spatial characteristics and analogue electronics calibration.
