Paper Abstract

An arrangement is presented for nonmechanical azimuth change or rotation of a linear polarizer that is followed by a photodetector. The arrangement uses a polarization modulator or variable retarder as the driving element for azimuth change interposed between a quarter-wave plate and the polarizer to be rotated. The polarization modulator or variable retarder is oriented with its fast axis at 45 degree related to that of the quarter-wave plate and the axis of the polarizer. Operation of the modulator or variable retarder results in a nonmechanical azimuth change or rotation of the polarizer equal to one half of the retardance of the modulator or variable retarder. The present arrangement, which can be used for constructing an azimuth-variable analyzer, has been verified by experiments.
