Michelson interferometer air speed measuring device

The utility model discloses a michelson interferometer air speed measuring device, include: testing platform is fixed in the shell on the testing platform, locates the michelson interferometer subassembly that testing platform went up and produced interference fringe, and both ends are fixed in shell and testing platform respectively and are experienced the elasticity post of wind pressure, set upon testing platform and aim at the michelson interferometer subassembly gather the interference fringe displacement diagram like the camera, the image information of receipt camera calculates the ARMtreater of wind speed. The utility model provides a michelson interferometer air speed measuring device, this device shell's structural design can avoid the bad weather to accuracy of measurement's influence, the utility model discloses based on the michelson interferometer method, like this can the extremely minor displacement of detecting object, through carrying out the automatic recording tointerference fringe and han
