ABSTRACT:
A PIV system provides a bias velocity component to each flow field speckle pattern recorded on a video array by rastering each corresponding recorded electrical image pattern by a select number of raster lines in the time interval prior to recording a succeeding speckle pattern image, thereby providing a calibrated spatial offset between recorded images.
