| Abstract | ||
| This work presents the study of the effect of the static pressure on the propagation of laser beam in the fibers. Three types of fiber have been used in this studies; multimode & step index fiber, Plastic Clad Plastic (PCP) with and with-out jacket and Glass core fiber (bare core). Normal pressure of rang (0 ~ 1300 ) bar were applied on a section (20 cm) length of fiber. The variation of power attenuation as a function of time during the applied pressure were also investigated .The sensitivity of each fiber was determined when used as a fiber optical pressure sensor. The results show PCP with jacket gives poor response to the pressure up to 500 bar, while glass core fiber fail as a sensor when the pressure is 1300 bar. PCP with-out jacket show two times sensitivity more when compared with other fiber under the same pressure used in this study. | ||
