Abstract

The airglow imaging interferometer for automatic remote sensing detection of upper atmosphere temperature and volume emissivity disclosed by the present invention comprises a tubular lens barrel, the inner wall of the lens barrel is sequentially provided with an incident diaphragm, a convex lens, a filter and a CCD detector from top to bottom. The imaging lens and the CCD detector are sequentially connected to the I / O interface of the Raspberry Pi and the computer through the data cable. The airglow imaging interferometer of the present invention is based on the FPI interference filter and the principle of "rotating spectral line temperature measurement method", uses filters to screen different diatomic and polyatomic airglow target light sources, and uses CCD detectors The interference fringes formed by the airglow are used for image acquisition, and at the same time, the 3rd generation B+ type of the Raspberry Pi is used to remotely control the CCD detector and realize information transmission, and the data analysis is performed on the computer and the results are displayed; the airglow imaging interferometer of the present invention has no moving parts, The measurement accuracy is improved and the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of remote sensing detection equipment, in particular to an airglow imaging interferometer for automatic remote sensing detection of high-level atmospheric temperature and volume emissivity. Background technique [0002] The atmospheric concentration in the middle and upper atmosphere (80-300km) is very low, its temperature changes greatly, and there are few means of detection of the upper atmosphere, resulting in the detection of the temperature of the middle and upper atmosphere becoming very slow in the past 30 years. The instruments for detecting parameters such as wind speed and temperature in the upper atmosphere include spaceborne and ground-based instruments and equipment. In 1991, the wind imaging interferometer WINDII (Wind Imaging Interferometer) and the high-resolution Doppler imager HRDI (High-Resolution Doppler Imager) carried on the upper atmospheric research satellite UARS (Upper Atmospheric R...
