【Abstract】 The moving Mirror scanning of the michelson interferometer controlled by microcomputer is reported.The uniformy changing of the opticl path difference and the light intensity-changing of the central interferometric fringe are experimental obseved.The spectrum of the incident light is also got by using FFT.更多还原
