一种弹性盘光纤加速度传感器的探讨

Study of a fiber optic accelerometer using a flexural disk

本文介绍了一种采用Ｍａｃｈ－Ｚｅｎｄｅｒ干涉仪结构的中心固支弹性盘光纤加速度传感器。该传感器利用弹性盘的变形引起光纤长度的变化，进而引起位相的变化，通过干涉仪感测出。文中分析了两种结构，并加以实现与对比。

A fiber optic accelerometer using a MachZender interferometer is described. The accelerometer was constructed using a central fixed flexural disk. Disk surface strains, caused by acceleration, are detected by fiber coils comprising the legs of a interferometer. Two flexural disk design are analyzed and compared.
