Reflective Linear Gradient Spectral Polarization Imaging Device

Abstract

The invention discloses a reflective linear gradient spectral imaging device, which is composed of a telescopic objective lens, a spectral polarization imaging component, a control circuit, and a computer control and image acquisition system. The spectral polarization imaging component consists of a reflective linear gradient filter component, a cylindrical lens, a miniature polarizer, a relay objective lens and a detector. In the reflective linear gradient spectral imaging device of the present invention, a reflective linear gradient filter assembly is used in the imaging optical path for light splitting, and rapid and continuous transformation is obtained by the rotation of the reflective linear gradient filter drum in the reflective linear gradient filter assembly. The spectrum is then passed through a cylindrical mirror and a micro-polarizer, and finally imaged on the target surface of the detector to obtain a spectral polarization fusion image at one time, which has the characteristics of high optical efficiency, high spectral resolution, and good real-time performance.
