Paper Abstract

A static and divided mirror Michelson interferometer is a new version of Michelson interferometer. It is designed to provide simultaneous measurements of dynamical signatures in the atmosphere. In this paper the theory of the survey of upper atmospheric wind field is first introduced. Then the design of this interferometer generally described and requirements of thin films are proposed. Using the software TFCALC, four thin films are successfully simulated, which can realize wide-angle and achromatic at the same time. The accuracy of the thin films can reach to 95.6% in reflection, 2.5° degrees in phase shift and 0.75° degree in wide angle.
