| Abstract: | Directed at the failure of the conventional machine-contact measurement to satisfy the especial state requirement of the surface of mobiles,the paper proposes laser double focus cross-correlation velocity measurement system,based on FPGA,synchronizing signal collection and disposal,high-speed logic apparatus FPGA and cross-correlation technology,and the system shows high-speed and high-precision advantages in the non-contact velocity measurement of kinds of mobile objects,and so it can find use in the measurement of the non-contact solid surface. |
