Abstract

The invention provides a polarization imaging device and a polarization imaging method of the polarization imaging device. The polarization imaging device comprises a liquid crystal lens and an imagesensor which are arranged oppositely. The liquid crystal lens comprises at least three liquid crystal layers which are parallel to one another and alignment layers and electrode layers matching the liquid crystal layers, wherein each liquid crystal layer is corresponding to the alignment angle of one alignment layer and the alignment angles are different from one another. The liquid crystal lens also comprises a voltage drive circuit which independently controls drive voltage applied to each liquid crystal layer. When the voltage drive circuit applies drive voltage to each layer of the liquidcrystal lens, the focal lengths of the liquid crystal lens units formed by the liquid crystal layers are the same. The device is provided with multiple liquid crystal layers and a polarizing film anda drive structure for adjusting the polarization direction of the polarizing film are not needed, so that the problem that the structure of a polarization imaging device in the prior art is not compact enough is solved.

Description

technical field [0001] The present invention relates to the technical field of polarization imaging, in particular to a polarization imaging device and method. Background technique [0002] Polarization imaging technology has a wide range of applications in the fields of earth remote sensing, astronomical observation, target recognition, medical diagnosis and three-dimensional reconstruction. The principle of polarization imaging technology is: when natural light (non-polarized light) interacts with matter, such as reflection, refraction, scattering, and absorption, the outgoing light will become partially polarized light or linearly polarized light in most cases. According to Kirchhoff's law and Fresnel's formula, the polarization degree of the outgoing light is directly related to the inherent properties of the material interface (such as composition, structure, roughness, water content, etc.), and the reflection angle (or refraction angle). Therefore, by analyzing the po...
