采用了双光束干涉的迈克尔逊干涉仪系统的傅里叶变换红外光谱仪，在动镜运动过程中，动镜可能在三个方向发生倾斜。
The Michelson interferometer system which has two-beam interference is applied in Fourier Transform interferometer, the moving mirror could tilt in three directions in motion.
本光栅干涉仪用光栅作为分束器，使双光束发生干涉。
The light is resolved by prisms, gratings, or by an interferometer.
