Signal-to-noise ratio enhancement of temporal phase unwrapping using video grating projection

Temporal phase unwrapping (TPU) has important application in fringe projection phase-shifting profilometry to measure multi-isolate objects and discontinuities surfaces. Due to the gray-scale standard of the digital projector, the gray-scale of the deformed pattern is of 256 at most. Suppose the fre...
