Compact complete imaging polarimeter using birefringent wedge prisms.

摘要: This paper describes a method for the mapping of spatially distributed states-of-polarization light with simple and compact configuration. A tiny block polarization-analyzing optics, consisting four thin birefringent wedge prisms sheet analyzer, are incorporated into an imaging polarimeter, such that mesh-like multiple fringes generated over CCD image sensor video camera. Fourier analysis obtained provides information determining two-dimensional distribution state-of-polarization. No mechanical or active elements analyzing polarization used, all parameters related to spatially-dependent monochromatic Stokes corresponding azimuth ellipticity angles can be determined from single frame. The effectiveness this is demonstrated by prototype incorporating calcite prisms.
