Phase shift via polarizer in an heterodyne interferometer
Author(s): A. S. Patra; Alika Khare

Paper Abstract

Polarization interferometry is normally not a regular topic in the class room at graduate level. Therefore a polarization heterodyne interferometer similar to a Michelson interferometer using polarizing components is discussed in this paper to demonstrate the interference of two orthogonal polarized beams. The measurement of the phase shift as a result of orientation of polarizer is performed by recording corresponding fringe shift. The theoretical expression is also presented using Jones calculus for the fringe shift as a function of azimuth of the polarizer. The experimental set-up is simple and can be very well incorporated in the teaching laboratory.
