An interferometric method for quantitative evaluation of the magnitude and direction of birefringence of an arbitrarily oriented birefringent sample is developed and presented. The analysis shows that full-field analysis of a spatially varying birefringence is possible by suitably combining several interferogram frames obtained by varying the polarization parameters involved. The preliminary experimental result for a uniformly birefringent sample with a known direction of birefringence is presented. © 2015 Society of Photo-Optical Instrumentation Engineersread more

Polarization phase-shifting interferometric technique for complete evaluation of birefringence
TL;DR: A full-field technique for simultaneous measurement of the magnitude of birefringence and its orientation is presented using a monolithic bireFringence sensitive interferometer where the interference fringes carry the information of both the biretringence phase and the orientation of the fast axis of an optically transmissive anisotropic material placed at the output of the interferometers.
