A cantilever optical-fiber accelerometer

Jerzy Kalenik , Ryszard Pająk

Abstract

A simple fiber-optic acceleration sensor has been designed and evaluated. It is an amplitude-modulation sensor, which employs inexpensive electronic instrumentation. The construction and technology of the sensor are presented. The influence of some construction parameters on sensor characteristics has been considered and measured. It is proved that simple construction modifications allow some sensor parameters to be tuned. The sensor characteristic is nonlinear. The amplitude-modulation depth reaches 50\% at an acceleration of 250 m/s2 for a cantilever length of 40 mm. The maximum operating frequency is dependent on cantilever length and for length 20 mm is 125 Hz.
