Abstract
A new phase-shift method based on the spatial phase modulated carrier fringe pattern is presented in this paper. The four phase-shifted fringe patterns, in which the phase differences between the adjacent pattern are n12, can be generated from only one fringe pattern, and all of the procedures can be done automatically. This method can be used in the condition of incoherent metrology and dynamic measurement.
