Abstract

This paper deals with simulation using (MATLAB) of optical fiber strain sensor employing the phase modulated technique in order to design a model for the Michelson interferometer, this paper also deals with the implementation of interferometer technique is considered and simplified because it has the ability to convert phase modulation to intensity modulation, in addition it has the ability to perform modulation frequency of interest signal which is equal to the optical frequency of the source. Thus by using this technique the detection of the signals of interests is achieved. The obtained results of sensor are done by varying the applied forces of sensing element, having various core diameters and calculating the strain. Also the result shows that the fiber optic Michelson sensor is very sensitive to measure the structural strain.
