“…Other examples of snapshot high-D systems include channeled imaging polarimeters, 51–53 which measure an I ( x , y , s ) dataset; line imaging spectropolarimeters 54,55 which measure I ( x , λ , s ); and computed tomographic imaging channeled spectropolarimeters 56,57 (CTICS), which measure I ( x , y , λ , s ). For polarization systems, the snapshot advantage in light efficiency is limited, since the theoretical maximum efficiency improvement over a scanning system is only 4 (for a Stokes polarimeter) or 16 (for a Mueller matrix polarimeter).…”

The snapshot advantage is a large increase in light collection efficiency available to high-dimensional measurement systems that avoid filtering and scanning. After discussing this advantage in the context of imaging spectrometry, where the greatest effort towards developing snapshot systems has been made, we describe the types of measurements where it is applicable. We then generalize it to the larger context of high-dimensional measurements, where the advantage increases geometrically with measurement dimensionality.

“…At present, only the interferential characteristics of light are taken good used to detect the object in the polarization interference imaging spectrometer (PIIS) system [5], but the polarized characteristics are usually ignored which means much valuable information may be lost. With the recent development of polarization interference imaging spectroscopy [6][7][8][9], the subject of polarization detection using these spectrometers has become more important which means more information could be got by one PIIS. Although a lot of different technological approaches of imaging polarimeters have been studied [10][11][12], the Fourier spectroscopy method is well known to possess the multiplex advantage [5].…”

“…When target is located in infinite distance, pre-optical system can be removed. It is clear that narrow slit in a dispersive device and DASI or spatially modulated interference imaging spectrometer can be replaced by the fieldview stop in PIIS [9,13,16] . Input ray is collimated by pre-telescope system, parallel ray is polarized by a linear polarizer P 1 and is split into two polarized components by a Savart polariscope.…”

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 25×25×12mm 3 in size. The lateral displacement is 1mm and transmissivity is about 90 percent in spectral range of 0.4~2.5 µm . 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.
