Paper Abstract

A pressure sensor based on fiber-optical sensor (FOS) is discussed about the design parameters option in this paper. An elastic spherical diaphragm is used as a reflective target of displacement fiber sensor in this paper. The spherical diaphragm coils when force is performed upon, light intensity of receiving fiber changes depending on the deformation of it. The relationship between sensitivities of the sensor and diameters of the elastic diaphragm, diameters of fibers and the distance from the terminal of fiber to the initial diaphragm before force performed are calculated based on light distributing theory. From the consequence of calculations, we give out the optimum condition for this kind fiber sensor design. The receiving intensity of light have a goood linear relationship to the fore is presented meanwhile.
