Full automatic atmospheric polarization mode image acquisition system and system control method

Abstract

A full automatic atmospheric polarization mode image acquisition system and a system control method are characterized in that the system comprises a polarization imaging module, a mechanical movement module, a brightness acquisition module and a system control and processing center; and the system control and processing center respectively controls the rotation angle of a base and the lift height of a worm in the mechanical movement module through a controller and records and processes the light intensity information acquired by a light intensity detector and the polarization image of sky area acquired by the polarization imaging module in a CCD camera. The invention has simple operation, accurate measurement result which is easy to calibrate, and does not need to mechanically rotate a polaroid sheet in the measurement process.

[0002] The surface of the earth is surrounded by a layer of atmosphere. The scattering of sunlight by the atmosphere is a very important optical phenomenon. It is the result of the interaction between light and matter. Scattering will produce polarized light. As a natural light source of transverse electromagnetic waves, sunlight is not polarized before entering the atmosphere. During the transmission process, sunlight is scattered and absorbed by air molecules and aerosol particles in the atmosphere, thus producing polarized light, and the specific polarization state distribution formed by different scattered light constitutes the atmospheric polarization mode.
