Paper Abstract

We report on the theoretical analysis, measurement and active rectification of depolarization caused by the differential transmission and phase shift of p- and s- polarized components of an axial beam passing through lens surfaces. Our theoretical analysis finds the polarization of output rays as a function of the input ray parameters, the shape factor and refractive index of the lenses used. For rays that are inclined to the optical axis we find optimal lens shape factors that minimize the rays' polarization aberrations. We report measurements of polarization aberrations that were detected in the back-focal plane of a modern microscope equipped with high numerical aperture lenses. Finally, we discuss strategies for polarization rectification and introduce new designs including a liquid crystal rectifier that can actively compensate a wide variety of polarization aberrations.
