Paper Abstract

The static wind imaging interferometer, based on a four-phase-divided mirror, is an attractive approach to acquiring the wind velocity and temperature of the upper atmosphere. Herein the operational principle of the interferometer is presented in detail. The throughput is theoretically analyzed with consideration of the reflections and transmittances of each systemic component. The throughput expression is derived by employing the Fresnel theorem. We conducted simulations, and the results show that the energy transmittance reaches 20% on the surface with high reflectivity-coating film when the inclination angle of the input light is limited to the range of -5 to +5 deg. The results presented herein provide a theoretical basis for the static design configuration and coating for the upper atmosphere wind imaging interferometer.
