Abstract: Based on the Michelson interferometer with a basic optical component,we use an optical method to measure the changes of pressure and refractive index within an area. Then synthesize the static and dynamic images by computer technology to obtain the lines of equal pressure of the air current field. Finally, the experimental phenomena is analyzed.
