Paper Abstract

An approach using fringe projection to perform the deformation measurement is proposed. A fringe pattern is illuminated onto the dynamic object, and a CCD camera is employed to record the fringe distribution. For a sufficient long recording time, 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 deformation during the measurement. Only one shot measurement is required for data processing. This makes it possible to perform the deformation measurements with low environmental vulnerability.
