Ｆａｂｒｙ－Ｐｅｒｏｔ干涉仪（简称Ｆ—ＰＩ）通常被用于小光谱范围和相对简单的光谱范围，然而近年来一些研究表明Ｆ—ＰＩ在超频谱范围内已完全可以和Ｍｉｃｈｅｌｓｏｎ干涉仪相媲美。［１］本文描述了一个较新的用Ｆａｂｒｙ－Ｐｅｒｏｔ干涉法和传统的加速度计相结合的仪器及其技术。它具有较小的尺寸和较高的分辨率，为测量低频微振信号提供了一种有效的仪器
Fabry-Perot interferometers (F-PIs) are often used for both small and relatively simple spectral ranges. However, some studies in recent years show that F-PI is perfectly comparable to the Michelson interferometer in the super-spectral range. [1] This article describes a newer instrument and its technique using Fabry-Perot interferometry combined with a conventional accelerometer. It has a smaller size and higher resolution, which provides an effective instrument for measuring low frequency vibration signals
