Abstract

A new computer-controlled Phase-shifting apparatus based on polarization techniques is developed. This apparatus changes the phase only by rotating a polarizer using a precision step motor. The precision of this method can be higher than other methods due to the accurate control of rotating angle. Several applications of this technique to optical interferometry and 3D shape measurements are presented.
