Abstract

A Novel Imaging Interferometer (NII) based on modified Michelson interferometer for surveying the physical properties of upper high speed atmospheric wind filed is presented. Taking the natural airglow and auroral visible emission lines in the upper atmosphere as surveyed source, NII can be used to retrieve the velocity and temperature of the upper high speed atmospheric wind field through the interference imaging spectroscopy coupled with the Doppler effect of electromagnetic wave. The optics system, survey principle, model and surveying method of four intensities are described. Simulated experimental of velocity and temperature of wind field is shown. NII has the advantages of wide field of view, bigger OPD, high resolution, achromatic, thermally stable, and is suitable for measuring upper atmospheric wind field.
