Paper Abstract

A phase-shifting method for circular grating Moire technique is introduced in this paper. The phase-shifting technique and the polarization method are combined to develop the phase- shifting of the circular grating Moire pattern, which is formed by Michelson interferometer through a series of simple components with some necessary polarization sections in the light path. It is a precise and applicable method and it can be performed in an ordinary situation.
