| Abstract: | A new dual-frequency laser Doppler velocity measurement method is presented in this paper.In this scheme,a parallelly linear-polarized dual-frequency laser incidents on the target and senses the target velocity with both of the frequencies,which can increase the maximum measurable velocity significantly.The theoretical analysis and verification experiment are presented,and the results show that high velocity measurement can be achieved with high precision using this method. |
