Abstract

A five-channel imaging spectropolarimeter (AFIS) aimed for airborne remote sensing applications is demonstrated. Spectral information is obtained by grating diffraction in AFIS, and spatial image is captured by the moving airborne platform. The full-Stokes polarization information is acquired by a polarization modulator consisting of 2 thick retarders and one linear polarizer. The AFIS works in push sweep mode, and the spectral information and polarization information of one-dimensional spatial pixels can be recorded by one camera shot. The AFIS is less sensitive to the vibration compared to time modulated imaging spectrometer, and it is more suitable for airborne remote sensing applications. The principle and feasibility are proved by simulations.
