| Abstract: | According to the DSCM,a new approach to measure the target angular vibration by a laser is put forward.The signal management in this method is realized by FPGA.This approach has several advantages of real time,remote sensing,simple structure and non-exigent for the capability of components.The transmitter module,receiver module and the signal processing module have been introduced.According to this new method,an experiment system has been developed and a preliminary experiment was conducted.The simulation and experiment results have shown that the method using laser speckle to measure real-time the target angular vibration is feasible. |
