摘要

激光散斑应变和位移测量是材料科学应用中一种成熟的非接触传感方法。本文模拟了激光散斑在衍射光波场自由场传播中的形成过程，衍射光波场在观测面上的强度分布为客观散斑图。激光散斑模拟的一个需求是分析不同测量装置的精度和灵敏度，以及分析由于试样表面结构变化、已知和未知物体的平移和旋转以及照明条件变化而引起的去相关效应。

Numerical simulation of coherent light diffracted from rough surfaces

Laser speckle strain and displacement measurement is a well established method for noncontacting sensing in material science applications. This paper deals with a simulation of the forming of laser speckles for free field propagation of the diffracted light-wave-field whose intensity distribution on the observation plane is the objective speckle pattern. A need for simulation of laser speckles is the analysis of accuracy and sensitivity of different measurement set-ups as well as the analysis of decorrelation effects due to structural changes on the specimen's surface, known and unknown object translation and rotation and changes in the illumination conditions.
