摘要：
Principle of the measurement of the upper atmospheric wind field using a Michelson interferometer with wide field, chromatic compensation and thermal compensation is briefly described. The modulation depth of the self-developed wind imaging interferometer is analyzed and calculated, and the expression of the modulation depth is derived. Computer simulation is adopted, and the dependence of the modulation depth on the angle is analyzed. The field of view of the wind imaging interferometer is 12.9 degrees when modulation depth is greater than 0.75, which fully shows the advantages of wide field and high modulation depth. The dependence of the modulation depth on the refractive index of glass is analyzed, and the optimized material is given. The dependence of the modulation depth on temperature is analyzed, and the curve is given. The research has important theoretical significance and practical value both for the research and development of the Michelson Interferometer with wide field, chromatic compensation and thermal compensation and the detection of the upper atmospheric wind field.
