A monocular 3D imaging system based on polarization-sensitive metalens

In this paper, a monolithic polarizing metalens is used to extract multiple polarization information of the target at the same time. The i1maging receiver uses a general detector easily available on the market, which can obtain the intensity information image of multiple polarization components. The polarization measurement speed is fast, and the number of modules in the optical system is reduced The monocular 3D imaging system based on polarization-sensitive metalens collects diffuse reflected light from the surface of the target, and uses different polarimetric sub-images obtained by the metalens to carry out 3D reconstruction of the target.
