Problems solved by technology

[0005] The disadvantage of the existing atmospheric gravity wave imager is that it only uses the change of atmospheric airglow intensity in the process to study the change of atmospheric gravity wave, and does not combine the influence of atmospheric temperature on gravity wave, so that the imaging results of atmospheric gravity wave are insufficient. persuasive
Moreover, the current atmospheric gravity wave imager is large in size, requires high ambient temperature, is not easy to carry, and is not conducive to field observation

Abstract

The invention relates to an airglow gravity wave multi-parameter detector. The airglow gravity wave multi-parameter detector comprises a shell, and a spectral temperature detection module and a large-view-field gravity wave imaging module which are arranged on the shell. The spectral temperature detection module comprises an optical window, a field diaphragm, an achromatic doublet lens, a first narrow-band interference filter, a lens, a first refrigeration CCD sensor and a first metal support from top to bottom. The large-view-field gravity wave imaging module comprises a hemispherical opticalwindow, a wide-angle lens, a first optical fiber light cone, a second narrow-band interference filter, a second optical fiber light cone, a second refrigeration CCD sensor and a second metal supportfrom top to bottom. The airglow gravity wave multi-parameter detector provided by the invention can detect the atmospheric temperature and the airglow radiation intensity at the same time, and multi-parameter observation is realized.

Description

technical field [0001] The invention relates to an airglow gravity wave multi-parameter detector, which measures atmospheric airglow layer O 2 (0-1) to invert the atmospheric temperature of the airglow layer, and to observe the atmospheric gravity wave by detecting the luminous intensity of the airglow, which belongs to the technical field of middle and upper atmosphere detection. Background technique [0002] Atmospheric science is an observation-based discipline that relies heavily on observation instruments, and so is the study of the upper atmosphere. In recent years, with the continuous advancement of science and technology, more in-depth research has been carried out on phenomena such as tidal waves and gravitational waves, so new challenges have also been raised for the development of observation instruments. [0003] At present, several types of instruments for measuring the temperature of the mesosphere region have been proposed in the world. The most representativ...
