摘    要:本文对散斑剪切照像术中傅里叶滤波平面的光场分布进行了讨论,得出滤波系统频谱面上的光场分布是以孔径函数的自相关和互相关的边界为周界;对最佳拍摄孔径的设计作了探讨,认为采用适当分离的孔径可以研善波效果,提高条纹的质量。实验的验证结果与理论相吻合。

关 键 词:散斑剪切照相术  孔径函数

Abstract:The light field distribution in Fourier filtering plane of speckle shearing photography is discussed in this paper. The conclusion is that the areas of light field are limited by the boundaries of autocorrelation and intercorrelation of the aperture functions. Theoretical analysis on optimum aperture functions, which could improve effects of filtering and the quality of fringe pattern is also made. Experimental resulta accord with the theoretical analysis.
Keywords:speckte shering photography  aperture function
