目前光弹性分析自动化的发展使得能够从光弹性试样中快速准确地收集等色线和等倾线参数。由于等色线参数产生主应力的差异，因此必须使用适当的程序来分离它们。本文综述了应力分离技术，以期将最合适的方法纳入自动全视场偏光仪。
Current developments in the automation of photoelastic analysis have enabled the fast and accurate collection of the isochromatic and isoclinic parametersl from photoelastic specimens. Since the isochromatic parameter yields the difference in the principal stresses then a suitable procedure has to be used for their separation. This paper provides a survey of the stress separation techniques available with a view to incorporating the most suitable method into an automated full field polariscope.
