Airglow imaging interferometer for detecting upper atmospheric temperature and volume emission rate in automatic remote sensing mode

Abstract

The invention discloses an airglow imaging interferometer for detecting an upper atmospheric temperature and a volume emission rate in an automatic remote sensing mode. The airglow imaging interferometer comprises a tubular lens barrel, wherein the inner wall of the lens barrel is sequentially provided with an incident pupil, a convex lens, an optical filter and an imaging lens of a CCD detector from top to bottom, wherein the CCD detector is sequentially connected with an I\O interface of a Raspberry Pi and the computer by means of data lines. The airglow imaging interferometer adopts the optical filter for screening different diatomic and polyatomic airglow target light sources based on an FPI interference optical filter and the principle of ''rotational line temperature measurement method'', adopts the CCD detector for carrying out image acquisition on interferometric fringes formed by airglow, controls the CCD detector remotely and realizes information transmission by utilizing a Raspberry Pi third-generation B+ type, and performs data analysis and displays a result on the computer; and the airglow imaging interferometer has no moving parts, improve the measurement precision and saves the cost.

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...
