单层光学薄膜中薄膜－衬底体系的双重干涉效应及其应用

Dual Interference Effects from a Single Layer Film Substrate System and Their Applications

提出了单层光学薄膜中薄膜与衬底反射光之间的双重干涉效应的理论，实验结果证实了理论分析的正确性。双重干涉效应使薄膜－衬底体系的热致反射调制度高达８０％。

The theory of dual interference effects (DIFE) from a single layer film and a substrate is proposed in this paper, the related mathematical expressions are obtained. The exprimental results have shown that our theoretical analysis is correct. As the result of DIFE, the thermo induced light intensity reflecting modulation depth is as high as 80%. The effects are expected to have widely potential applications.
