| Summary: | The main purpose of this project is to design and to build fiber optic microbend
sensor, measure the output power, power loss and analyze the results. The title of this
project is fiber optic microbend sensor. This project consists the transmitter and the
receiver between the fiber optic. This project will develop a sensor system that used
fiber optic cable, which is consisting of light source, sensor element and the light
detector. In normal condition the certain level will measure and if the sensor senses
some pressure it will change the level and indicate the level of pressure. In fiber
system, the optic wave is converted into an electric current by a photodetector. The
power detect at the receiver is depend on the power feed at the transmitter and the
attenuation of the fiber optic. When the cable in a straight line condition, the
attenuation will be minimum but if there is bend or indentation on the cable, there
will be additional attenuation on the cable because some of ray light will be reflected
so the power at receiver will be drop. This power differences will show that the fiber
optic cable can be use as microbend sensor. This project contains calculation,
simulation, design and analyze result. |
