Spectral polarization integrated imaging system based on spatial dimension coding and design method thereof

Abstract

A snapshot spatial dimension spectral polarization integrated imaging system and a design method thereof are provided. An objective lens generate an image of a target on a DMD; the DMD is disposed on a focal plane of the objective lens and connected to the computer; the computer controls an encoding matrix loaded on the DMD to encode information; the light is reflected to the primary mirror after being encoded, and then is reflected by the primary mirror to the convex grating for dispersion; the light is then reflected to the third mirror; an encoded image is produced on the micro polarizer array detector; polarization channel coding is completed; the micro polarizer array detector is connected to the computer; and the computer resolves compressive spectral polarization image based on spectral polarization coding data cube obtained on a target surface of the micro polarizer array detector.
