The polarizing Michelson interferometer of wind measurement based on polarization arrays is a interferometer for detecting atmosphere temperature and wind velocity. It is based on the principle of polarization interference. Four polarizers whose polarization orientation has an interval of 45° in turn attach to the front of detector. Four beams of light from four-plate pyramid prism pass polarizers. Then four different interferential intensities are formed at the same time on the detector. Then wind velocity and atmosphere temperature will be deduced from the intensities. This imaging process is simulated and emulated. The result after data processing is coincident with true value. The interferometer offers advantages including simple and steady construction and high precision. It is fit for detecting fast goal.
