Abstract

A pulsed-encoding scheme for phase-shifting projected fringe profilometry is presented. The projected fringe patterns used to perform the phase-shifting technique can be used to identify the fringe orders directly. For the filed of view 300mm×300mm, systematic accuracy was approximately 600μm.
