光弹性测量中的位相展开

Phase Unwrapping in Photoelasticity

根据调制度排序，提出了一个新的用于模型全场光弹条纹级次测量的位相展开方法，并进行了实验验证。在位相展开区域的边界上，位相展开的路径由像素的强度调制决定。这个方法的优点是很明显的，即使在最坏情况下，其误差也限制在局部最小区域上。

Based on the modulation ordering, a novel phase unwrapping algorithm for measurement of photoelastic fringe orders in the whole field of a model is put forward. The path for phase unwrapping is determined by the intensity modulation in the pixels on the boundary of the phase unwrapped areas. The algorithm is very superior, and in the worst case the error, if any, is limited to local minimum areas.
