Abstract

The invention discloses a ground-based airglow imaging interferometer, which comprises a longitudinal optical axis part and a transverse optical axis part. The longitudinal optical axis part is sequentially arranged with a field diaphragm, a lens group A, a polarizer A and Large air-gap wide-angle Michelson interferometer; the lateral optical axis part starts from the large air-gap wide-angle Michelson interferometer, and LCoS reflective liquid crystals are arranged at intervals on one side of the lateral optical axis of the large air-gap wide-angle Michelson interferometer. The other side of the air-gap wide-angle Michelson interferometer in the direction of the transverse optical axis is sequentially arranged with a polarizer B, a lens group B, a lens group C, a narrow-band interference filter, a lens and a CCD camera. The invention also discloses a detection method for the wind speed and temperature of the upper atmosphere at the same time. The device and method of the invention can realize the simultaneous detection of upper atmospheric wind speed and temperature, and has high detection accuracy.

Description

technical field [0001] The invention belongs to the technical field of detection of upper atmosphere by interferometry, and uses LCoS-based large air gap wide-angle Michelson interferometer and Fabry-Perot interference filter to simultaneously realize phase four-step wind measurement and rotating spectral line temperature measurement, It specifically relates to a ground-based airglow imaging interferometer; the invention also relates to a method for simultaneously detecting high-level atmospheric wind speed and temperature by using the ground-based airglow imaging interferometer. Background technique [0002] Measuring wind speed by optical interferometry is the main method of passive remote sensing to detect upper atmospheric wind field. Among them, the "four-intensity" wind measurement method with the help of a wide-angle Michelson interferometer (MI, Michelson interferometer) was proposed by the G.G. Shepherd research group in Canada in 1966. After continuous research and...
