Abstract
An algorithm using fringe projection to perform the speed measurement is described. A fringe pattern is illuminated onto the dynamic object, and a CCD camera is used to record the fringe distribution. Fringes on the obtained image are deformed by the topography of the object, and also, blurred by motion. Thus, the blurred fringes supply additional information to describe the speed of motion. Only one shot measurement is required for data processing. This makes it possible to perform the speed measurements with low environmental vulnerability.
