Embodiment Construction

[0014] In combination with the technical scheme and accompanying drawings, the technical implementation mode of the present invention will now be described in detail. When using this test system, system installation must be performed first. When assembling the polarization measuring head 1, install the cylindrical rotating head 2 on the inner side of the interface one 3, slightly tighten the fastening screw 14 to ensure that the rotating head will not fall and can rotate, and at the same time connect the main optical axis of the polarizer with the rotating head Align the 0-degree reference optical axis with the 0-degree reference optical axis, then place the disc-shaped polarizer 1 in the inner cavity of the rotating head 2, press it with the ring pressure ring 12 and fix it on the rotating head 2 with two screws 13; put the equator The instrument 5 is installed on the tripod 6, and then the refractor telescope 4 is installed on the top of the equatorial mount to ensure that t...

Abstract

The invention relates to a radiation spectrum measurement system of the sky polarized light, belonging to the optical electron testing technology field, which is applicable to measuring the sky polarized light and spatial and temporal distribution analysis. The measurement system is consisted of a polarization measurement head, a telescopic optical system, a fiber spectrometer system and a computer. Arranging the polarization measurement head comprises: arranging a cylindrical rotary head on the inside of an interface (1); screwing down a ding screw; then putting a wafer-shaped polarizer in the lumen of the rotary head; using an annular pressing ring to compress and fix the polarizer on the rotary head via two bolts. An equatorial is arranged on an A-frame. Then a refractor is arranged above the equatorial. The back-end of anti-ultraviolet optical fiber is connected on a spectrograph. Then a cosine corrector is arranged on the front-end of the anti-ultraviolet optical fiber. And then the probe-end of the cosine corrector is inserted into an interface (2) and the ding screw is screwed down. The system is provided with strong currency, wide application range and convenient operation.

Description

technical field [0001] The invention relates to a radiation spectrum measurement system for polarized light in the sky, belongs to the technical field of optical and electronic testing, and is suitable for the measurement of polarized light in the sky and the analysis of its temporal and spatial distribution rules. Background technique [0002] Most of the traditional polarization measurement systems use the optical radiation detection method, that is, to obtain the radiation intensity of a specific target, and then use the polarization of light to detect the target. These test systems can realize the polarization measurement of a fixed target and the time distribution analysis of polarized light in the sky. However, due to design limitations, the azimuth and altitude angles of the test target cannot be adjusted conveniently, so it is impossible to achieve any angle in the sky. Polarization measurement and spatial distribution analysis of atmospheric polarization. For examp...
