Paper Abstract

A new type of accelerometer is advanced which is based on optical fiber multi-mode interference (MMI). We use a structure that a multi-mode fiber connected to two single mode fibers as the sensing part of the accelerometer. By measuring the changes of the output spectrum can get the acceleration. This paper describes the principle of the accelerometer based on multi-mode interference, and a theoretical simulation is performed. In the experiment a Piezoelectric Ceramic is applied to simulate the Static Acceleration. The result manifests that this type of accelerometer has a great dynamic range and a good resolution, also it's easy to fabricate and low cost.
