Abstract
A novel system for mapping the spatial distribution of a time varying state of polarization (SOP) is developed on the basis of optical heterodyne detection techniques using the Fouriertransformation for fringe analyzing. A signal beam is photomixed over a photodetector array with a local oscillator beam consisting of orthogonal linearly polarized twofrequency components. The generated beat photocurrent is composed of two beatcomponents that include information about the orthogonally polarized components of the signal beam. The amplitude ratio and phase difference of these two beatcomponents can determine the spacetime variations of the SOP. 1 .
