摘要：

A use of the multichannel phase stepped interferometry approach to automated fringe pattern analysis in moire interferometry is described. Polarization optics is used to implement the appropriate phase shifts in each channel. The channels are created by inserting a diffraction grating at the output of the interferometer. It is possible to work at one frame rate. This system enables studies in unstable environmental conditions and studies of time dependent events.
