Paper Title
Intensity Modulated Fiber Optic Three Dimensional Vibration Sensing System
Abstract
A novel method is demonstrated for the design of three-dimensional non-contact fiber optic vibration sensor based
on simple principle of reflected light intensity modulation. A bunch of optical fiber fibers have been arranged to detect
vibration in axial, vertical and horizontal directions. The rational output technique implemented to discriminate the acquired
signals from each other for their respective direction of vibrations. A LabVIEW program was used to simplify the analysis and
to monitor the three dimensional vibration in real time applications. The experiments carried out to study the displacement
response of the sensor to calibrate, and also tested the sensor response for vibration in different directions. It is found that the
system can measure the three dimensional vibration at a point without any contact to it.
