摘　　要：研究了光学层析卷积反投影算法中滤波函数的性质和作用,导出并分析了全息干涉法测量和光束偏转扫描测量中的滤波函数.The property of and the role played by the filter function for the convolution back-projection algorithm is studied. Low-pass and band-limited filter function is selected to suppress the high frequency noise. The filter function for holography interferometry and for scanning. measurement with deflected light beam are derived and discussed.
