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...

Problems solved by technology

[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. In addition, the post-stage signal processing circuit used in the existing device is relatively simple, and the interference and noise processing of the actual signal are not fully considered. The atmospheric polarization information Acquisition accuracy is not high

Therefore, the practicability of existing devices and systems is not strong, which is not conducive to the integration of multiple detection devices or systems; and the signal stability and anti-interference ability of existing devices and systems are weak, which affects the accuracy of atmospheric polarization information detection results.
