摘要
从理论上研究菲涅耳双棱镜对于光的传播的影响以及发生干涉的光之间的物理关系即入射角与干涉位置的关系,同时从实验计算的角度论证等效法的可行性,即从实验观测出发通过数值计算的方法证明等效前后用于分析干涉光强分布情况的光程差计算结果相等.
The route of light in Fresnel biprism and the relationship of some physical quantity describing interference were studied.The feasibility of the method of equal effects was confirmed by experiment.Numerical calculation showed that the optical path difference before and after the application of the equal-effects method used,was equal.
