Abstract

The purpose of this paper is to analyze the inherent and induced effects of the perturbations that result in losses of the optical power on the fiber measuring element of pressure/force detectors. Inherent or induced perturbations result in losses of the polarization state and optical power on the fiber. The presence of outer mechanical stress (pressure or tensile force) on the fiber results in the microbending loss phenomenon embedded in the optical fiber. The paper deals with both modeling and simulating the sensor behavior and with measurements on a physical sensor.
