Double Polarization Modulation Interferometry

Volume 51, Number 6 (June 1997) Page 770-777

Polavarapu, Prasad L.

The concepts of a double polarization modulation interferometer and the experimental measurements verifying these concepts are presented. This interferometer serves as an analytical tool for the characterization of polarization modulation devices. In addition, for polarization difference measurements this interferometer offers four times better efficiency over widely used amplitude-division interferometers.
