Lenslet-based snapshot full-Stokes imaging spectropolarimeter

A lenslet-based snapshot channeled imaging spectropolarimeter (SCISP) system is presented. By introducing the multiple-image Fourier transform imaging spectrometer into the archetype of channeled spectropolarimetry, SCISP can simultaneously acquire the three-dimensional spatial and spectral (x, y, lambda) data-cube for each of the Stokes parameters S-0, S-1, S-2 and S-3 in a snapshot using a single detector. The validity and accuracy of SCISP are showcased by attaining the outdoor spectral-polarimetric video and different laboratory accuracy experiments. Unlike conventional channeled spectropolarimeters, SCISP maintains the real snapshot feature (2D spatial im-aging) and it is compact, robust. These capacities of the camera open new prospects for many applications, such as remote sensing, space exploration, and biological analysis.
