摘要
通过琼斯矩阵推导出一般平面偏振场的受初应力影响的光强等式 ,选用有边缘效应的直边、斜边和曲边三种常见边界形状的光弹性模型 ,用五步彩色相移法分析了初应力对等倾角的影响 。
Intensity equations for the general plane polariscope with initial stresses existing in the photoelastic models are deduced by Jones′s matrix. The influence of initial stresses on isoclinics is estimated qualitatively and quantitatively by five step color phase shifting analysis for several models with rectilinear, diagonal and circular boundary. The technique is successful.
