Paper Abstract

A laterally sheared beam splitter-savart polariscope was developed based on a single birefringent component. It is a key part in a novel polarization interference imaging spectrometer. The Savart polariscope consists of two paralled plates of calcite cut at an arbitrary angle to the optics axis and can split up a ray of light incident on the surface into an ordinary ray and an extraordinary ray. The output rays are paralled laterally sheared. The Savart polariscope is 25×25×12mm3 in size. The lateral displacement is 1mm and transmissivity is about 90 percent in spectral range of 0.4~2.5μm. A static polarization imaging spectrometer based on a Savart polariscope has advantage of ultra-compact size, wide field of view, high throughput and without any moving parts. The principle and construction of Savart polariscope are described, and the experimental results of the interference imaging spectrum are given.
