Embedded polarimetric differential stress sensor

摘要

Abstract: This paper describes the design and testing of an embedded fiber optic sensor with high sensitivity and broadband response. The sensing principle is based on the observation of stress-induced birefringence in an optical fiber embedded in a flat panel. The sensor was designed to measure low-level stresses in sea ice, however, the sensing principle and measurement techniques presented here have general application for embedded stress and pressure sensors. !13
