Plane four-channel atmosphere polarization information detection sensor

Abstract

A planar four-channel atmospheric polarization information sensor, characterized in using highly integrated modular design, comprises a sensor physical structure module, a polarized light selecting and sensing module and a sensor hardware circuit module, wherein the sensor physical structure module has a columnar cylinder, the above of which is embedded with the polarized light selecting and sensing module being arranged in planar four-channel and corresponded with four-channel polarized light transmission channel in the columnar cylinder to a four-channel unblocked optical pass; the sensor hardware circuit module is embedded below the columnar cylinder for receiving current signal outputted from four photoelectric converters arranged in the four channel polarized light transmission channel, and simultaneously performing a series of signal processing to the current signal, so as to provide reliable, accurate signal input for successive atmospheric polarization information calculation and processing.

Description

technical field [0001] The invention belongs to the technical field of intelligent information acquisition and bionic robot navigation, and relates to a measuring device for atmospheric polarization information, in particular to a plane four-channel atmospheric polarization information detection sensor. Background technique [0002] Sunlight itself is a natural light source, but it is scattered and reflected by particles in the atmosphere during atmospheric transmission, such as by O 2 and N 2 molecules, which produce correspondingly polarized light. Sunlight with different polarization directions and different polarization intensities forms a specific atmospheric polarization mode. Atmospheric polarization mode information mainly includes parameter information such as atmospheric polarization degree and polarization direction. Atmospheric polarization mode is closely related to geographical location, sun position, atmospheric environment, weather conditions, and even gro...

[0004] Due to the complexity of atmospheric polarization mode information, the measurement of atmospheric polarization mode information needs to be repeated for a long time

However, the atmospheric polarization information measurement device mentioned in the patent specification with application number 200610040467.4, as well as the existing photoelectric model-based atmospheric polarization information detection device and equipment, basically do not adopt a modular design, and the overall structure of the sensor is relatively complicated. The integration level is not high, which brings many inconveniences in the actual detection
