首先阐述了分析光弹性力学图象条纹的普遍有效方法，并利用光强I与图象条纹级数N之间的三角函数关系，推导出象素点灰度Z与条纹级数N对应关系式，从而得到力学参数。
Using the trigonometric function relation-ship between the light intensity / and the image fringe order N , the equations of the fringe order N on brightness Z are deduced , and the mechanical parameters are thus obtained .
