Abstract

The invention provides a dayglow temperature photometer and a method thereof for detecting airglow spectrum intensity and temperature. An echelon grating and a narrow-band interference filter are organically combined to serve as a core device of the dayglow temperature photometer, and luminous intensity and temperature of dayglows in an upper atmosphere are detected simultaneously by utilizing a high-resolution spectroscopic method and a rotational spectral-line temperature-measuring method. The dayglow temperature photometer comprises four portions including a light guide system, a telescopic system, a light splitting system and an imaging system which are sequentially arranged.

Description

Technical field: [0001] The invention relates to a daytime airglow temperature photometer and a method for detecting airglow spectral intensity and temperature thereof, belonging to the technical field of upper atmosphere detection. Background technique: [0002] The use of natural luminous airglow throughout the day as a light source to passively detect atmospheric properties (temperature, wind speed, luminous intensity, trace particle density and abundance) through passive remote sensing is the main method for studying the physics of the upper atmosphere. [0003] The detection of luminous intensity and temperature of night airglow is relatively mature. Usually, the rotational spectral line temperature measurement method is used, which is realized by a photometer composed of a narrow-band interference filter and a photomultiplier tube or a CCD (Charge Coupled Device). Rate information and dynamic characteristics. Representative instruments include MORTI (Mesopause Oxygen...
