Paper Abstract

In this paper, the feasibility of multimode fiber as pressure sensor is explore by using the straight structure of the fiber itself. The elastic mechanical model and the basic equation of the straight structure of the fiber is established. ANSYS software is used for the analysis of stress and strain distribution and the results show that the stress and strain of load section fiber are linearly related. In the experimental process, the straight structure fiber is used as the test unit and the change of the optical power is measured and analyzed during the pressure loading. The experimental results show that the linear correlation coefficient R2 of the pressure loading process from 0g to 400g is 0.9117 for the multi-mode fiber; and the linear correlation coefficient R2 of the pressure unloading process from 400g to 0g is 0.7061. So it can be concluded that the straight structure multimode fiber can be used as a pressure sensor.
