| 摘 要： | 在光弹应力分析中，利用分数级条纹可以提高分析精度，于是，产生分数级条纹的方法研究就变得非常重要。利用图像处理技术，首先采集一幅图像，然后通过对这幅图像的算术运算就可以产生分数级条纹。给出了详细的理论分析，并进行实验。利用本文方法，在两条整数级条纹之间，可以相继产生７条分数级条纹。

| Abstract: | In photoelastic stress analysis, the accuracy of
analysis can be improved by using fractional isochromatic fringes, so it is very important to
study the approach for producing fractional fringes. By using image processing technology, a
fringe pattern is captured firstly, then fractional fringes can be produced by arithmetic operation
to the fringe pattern. Theoretical analysis is given in detail, and experiments are carried out.
Seven fractional fringes are produced between two integer fringes by using the technique. |
