Abstract

The objective of this paper is to present a detailed investigation of the frustrated-total-internal-reflection (FTIR) phenomenon in silica-glass-based optical fibers and its application to simple intensity-modulated strain and pressure sensors. Such sensors may be readily fabricated using silica-based fibers and can be easily modified using sapphire fibers for high temperature industrial applications where conventional silica-based fiber sensors are not feasible. In this paper we present the all-fiber FTIR sensor and show good correlation between theory and experiment. We also present results for the design and implementation of a prototype FTIR-based fiber pressure sensor.
