Abstract: Upper atmospheric wind and temperature are important basic parameters. Its global high-precision measurement has broad prospects for various applications, so the strong demand to explore them is growing the interferometric spectrometer is characterized with multi-channel, high-throughput and high spectral resolution, it becomes the optimum choice for detecting upper atmospheric wind and temperature. The current successful application of the interferometric spectrometer has two kinds, Fabry-Perot interferometer and wide angle Michelson interferometer. The paper mainly reviews the interferometric spectrometers used in the upper atmosphere wind and temperature field exploration, analysis and compares the feasibility of several interferometers measurement of wind and temperature and their respective advantages and disadvantages. These work lays a foundation for our future on-board detection in China. -
