| Abstract: | A heterodyne detection experiment is established to measure the constant rotation velocity and the variable velocity of targets,in which the diffuse reflectance target and simple harmonic motion model are taken as research targets.For uniform rotation velocity measurement,the heterodyne method and amplitude modulation velocity measurement are conducted at the same time to measure the rotation velocity of a diffusion target in two directions and 133 sets of results are obtained.Moreover,the variable velocity... |
