Embodiment Construction

[0027] In this embodiment, an automatic measurement system for the whole-sky area atmospheric polarization mode includes: a whole-sky area information acquisition module, a three-channel polarization module, and a control module; figure 1 Shown is an optical path structure diagram composed of a full-sky information acquisition module and a three-channel polarization module. The full-sky information acquisition module receives the full-sky light source for adjustment, and outputs the optimal optical path of the full-sky beam to the three-channel polarization module; The three-channel polarization module converts the information type of the full-sky beam of the optimal optical path, and outputs the three-channel full-sky polarization image information to the control module; figure 2 As shown, the control module establishes communication with the three-channel polarization module to control the three-channel polarization module for image acquisition and transmit data to the control ...

Abstract

The invention discloses an automatic measurement system of omnimax atmospheric polarization pattern. The automatic measurement system is characterized by comprising an omnimax information acquisition module, a three-channel polarization module and a control module, wherein an omnimax light source input system outputs an omnimax light beam of an optimal light path to the three-channel polarization module through the omnimax information acquisition module, the three-channel polarization module converts the information category of the omnimax light beam of the optimal light path and outputs omnimax polarization image information to the control module, the control module controls the three-channel polarization module to collect the omnimax polarization image information, and outputs omnimax atmospheric polarization pattern information through stokes vector algorithm processing and calculation. The automatic measurement system can be used for collecting the omnimax polarization image information in three different polarization directions under the same view field and acquiring the omnimax atmospheric polarization pattern information so as to eliminate the error.

Description

Technical field [0001] The invention relates to the field of atmospheric optics research and intelligent information acquisition, in particular to an automatic measurement system of the atmospheric polarization mode in the whole sky. Background technique [0002] As a natural light source, sunlight will be scattered due to the effects of particles such as aerosols in the atmosphere during the transmission of the atmosphere, and unbiased natural light will be converted to produce polarized light. A large amount of sunlight will form a specific polarization state distribution in the atmosphere after the action of particles, that is, the atmospheric polarization mode. The atmospheric polarization mode can be expressed by the atmospheric polarization degree and polarization direction. Studies have found that the distribution of atmospheric polarization modes has a certain regularity and changes regularly throughout the day. At a certain time of the day and at a certain place, due to...
