Abstract

The invention provides a long-wave infrared Doppler differential interferometer system supporting structure, which solves the problems of micro-thermal stress, low-thermal deformation and the like ofa long-wave infrared Doppler differential interferometer complete machine during the temperature changing process. The supporting structure comprises a lens group, wherein lenses in the lens group arecompressed and fixed axially and elastically, and a field-of-view expanding prism 1 is compressed and fixed axially and elastically and a field-of-view expanding prism 2 is compressed and fixed radially by means of spring plungers, thereby effectively reducing the influence of temperature change on interferometer optical components, and ensuring the phase inversion precision and wind measurementprecision of the long-wave infrared Doppler differential interferometer.

Description

technical field [0001] The invention relates to a system support structure of a long-wave infrared Doppler differential interferometer. Background technique [0002] The earth's atmospheric environment is a very complex dynamic system, which refers to the physical, chemical and biological characteristics of the air on which organisms live. Among them, the characteristics of temperature, humidity, and wind speed caused by solar radiation are important parameters for detecting the atmospheric environment. [0003] Wind field detection in the middle and upper atmosphere is an important means to characterize the atmospheric environment and atmospheric dynamics, and it is of great significance for accurate weather forecasting and the smooth progress of the aerospace industry. The Doppler differential interferometry technology is based on the Michelson interferometry technology, which is improved on the basis of the spatial heterodyne interferometry technology, and the wind speed ...
