薄膜干涉反射光半波损失计算的讨论

Discussion on Calculation of Half-wave Loss of Reflection Light in Thin Film Interference

从薄膜干涉现象及半波损失概念出发 ,分析讨论透明薄膜所处介质折射率不同时 ,反射光因半波损失所引起的额外程差的计算方法 ,作为《光学教程》中讨论额外程差的补充 。

The calculation method of additional path difference of reflection light caused by half-wave loss is discussed .When mediun index of reflection of transparent thin film is different,it can be used as addition to the discussion on additional path difference in the course of “Optics”;and some amendments to the conditions of thin film interference and the expression of its results are submitted.
