Abstract

The invention discloses a liquid-crystal-based infrared wave beam polarization control chip. The liquid-crystal-based infrared wave beam polarization control chip comprises a chip shell (4) and an array liquid crystal polarization control structure (3) located in the chip shell (4). The chip shell (4) is provided with a first drive control signal input port (1), a second drive control signal input port (2), a third drive control signal input port (5) and a fourth drive control signal input port (6). Infrared light waves are dispersed into a sub-wave-beam array according to the array scale and the arrangement situation of the liquid crystal polarization control structure after entering the array liquid crystal polarization control structure of the chip. The specific polarization-state transmission beam wave is obtained by making sub-wave-beams interact with liquid crystal molecules excited by a controlled electric field, conducting phase delay operation in the horizontal direction, the vertical direction, the 45-degree direction, the 135-degree direction and the like and then conducting beam combining. The liquid-crystal-based infrared wave beam polarization control chip is compact in structure, and electronic control establishment or solidification or modulation in the infrared wave beam polarization state can be conducted.

Description

Technical field

[0001] The invention belongs to the technical field of precise measurement and control of infrared beams, and more specifically relates to a liquid crystal-based infrared beam polarization control chip. Background technique

[0002] Generally speaking, the infrared radiation emitted from artificial light sources such as coherent lasers or a variety of hot and cold light emitters all have a specific polarization state. The relatively uniformly polarized infrared light emitted by the sun, the earth and other stars, after being scattered, reflected, transmitted by the atmosphere, or interacted with other material structures, presents a fixed polarization form affected and restricted by the physical properties of the propagation medium, such as typical linear polarization, Circular polarization and elliptical polarization, etc. The material structure of a specific shape and energy state, based on the intrinsic resonance response of the inherent electromagnetic framew...
