Abstract
In some of the optical fiber pressure sensors, the pressure on the fiber is converted to the strain along the fiber by a mechanical transducer and the strain is measured. As the transducer causes many limitations in sensing process, we used stimulated Brillouin scattering generated dynamic grating for distributed measurement of direct pressure without any transducer in this paper. The sensitivity of the dynamic grating characteristic to the pressure loaded on the fiber for a two side holes fiber is calculated, for the first time. The effects of the fiber parameters on the pressure sensitivity of dynamic grating are discussed.
