Technology Research of Fine Tracking Unit Based on AOD for Laser Communication

摘要：

In the paper, we obtained that the response of the FSM on the order of kHz sinusoidal perturbation signal has serious distortion, in the case of increasing the frequency of the disturbance signal, and the phase delay of AOD response is only 1％ for kHz sinusoidal perturbation signal in the fine tracking unit of free space laser communication through the analysis, modeling, simulation and a series of work. It shows that by using AOD replace traditional FSM in the precision tracking system, its bandwidth can be improved largely, then, it has a further suppression of the residual error and obtains a higher tracking accuracy.
