An optimized method was proposed to get high resolution and wide-view images of infrared target. To overcome the shortcoming in the traditional ways that had the contradiction between wide-view and high resolution, this experiment scheme was designed that adopted pendulum scanning of whole system along with synchronal image motion compensation. It was shown that the precise speed control and image motion compensation performed decisive roles for the successful achievement of the whole system. Whats more, optimized design had been made for these two parts. The experiment and simulation results are in good agreement. Accordingly, the engineering feasibility of the proposed design method has been validated. The experiment results show that the velocity error of the system is 0.19%. After synchronal image motion compensation, the obtained infrared images have both wide-view and high resolution.
