After analyzing the relationship between the subdividing error and the sinusoidal index  a low-pass digital filter which can make the moire signal satisfy the need of 1024 subdivision is designed. Considering with the fundamental frequency varies with the rotating speed of encoder  the tunable filter is adopted  whose cutoff frequency is calculated according to the coarse information of the encoder. The simulating results show that the proposed method can improve the sinusoidal index  especially at high rotating speed. At last  the compensating algorithm is implemented in the terminal of satellite optical communication  which needs high resolution. The experimental results show indicate that the developed method is feasible. 2011 IEEE.   Large-deformation analysis in microscopic area using micro-moire methods with a focused ion beam milling grating 期刊论文  OAI收割 Optics and Lasers in Engineering, 2007, 卷号: 45, 期号: 12, 页码: 1157-1169 H.
