中文摘要：

在米切尔森干涉仪的光子运动以几何光学和波浪光学被重新分析。在一个重力的波浪的背景的光子的古典路径从 Fermat 原则被导出，它与在一般相关性的空 geodesics 一样。使变形的麦克斯韦方程和在一个重力的波浪的背景的电场的波浪方程在扁平空间的近似被介绍。两个方法证明甚至干涉仪的反应的信封取决于一个重力的波浪的频率，但是镜子颤动的频率几乎独立。

英文摘要：

Photon motion in a Michelson interferometer is re-analyzed in terms of both geometrical optics and wave optics. The classical paths of the photons in the background of a gravitational wave are derived from the Fermat principle, which is the same as the null geodesics in general relativity. The deformed Maxwell equations and the wave equations of electric fields in the background of a gravitational wave are presented in a fiat-space approximation. Both methods show that even the envelope of the response of an interferometer depends on the frequency of a gravitational wave, but it is almost independent of the frequency of the mirror＇s vibrations.
