散斑干涉法实现三维物体相减

Subtraction of 3 D Objects with the Speckle Interference Technique

本文把Ｆｒａｎｃｏｎ所提出的散斑图象相减方法推广到三维漫反射物体的相减。采用多次曝光技术，提高了相减象的质量。实验结果与理论分析符合得很好。并且获得高质量的输出结果。

The Francons speckle image subtraction technique is suitable to 3 D diffusing objects. The quality of the subtraction image is improved by the multi exposure. The experimental results are in good agreement with the theoretical analyses.
