摘要A novel method for velocity measurement is presented. In this scheme, a parallel-linear-polarization dual-frequency laser is incident on the target and senses the target velocity with both the frequencies, which can increase the maximum measurable velocity significantly. The theoretical analysis and verification experiment of the novel method are presented, which show that high-velocity measurement can be achieved with high precision using this method.
