白光散斑照相术的部分相干理论及其应用

The Partially Coherent Theory for White—light Speckle Photography and Its Applications

本文从光的相干性的角度出发,用部分相干理论分析了白光散斑照相过程。讨论了影响象面散斑对比度的诸因素,并对我们在此理论指导下完成的部分实验工作作了简介。

Based on the coherence of light,an analysis of white-light speckle pho- tography is given by using partially coherent theory.The mutual coherence function that can simultaniously reflect temporal and spatial coherence is derived.The contrast of image white-light speckles is discussed on the basis of intensity formula of a pair- point object imaging.Some experimental studies based on this theory are briefly intro- duced.
