Under the condition of total reflection can be achievd a quarter wave plate in single waveleugth or wide wave length by means of matching a prism with a single layer or multilayer dielectic thin film. 在全反射条件下
The effect of dichroic and retarded quarter wave plate in the experiment are discussed by the analysis to the fringe of photoelastic strains. 通过光弹性应力条纹的分析，具体讨论1/4波片具有延迟差和二向色性时对本试验的影响.
