Interaction model between fiber optic ultrasonic sensor and matrix materials

Abstract

A dynamic model of a fiber segment with polymer coating, which was embedded in the concrete materials, is proposed to evaluating the response of the ultrasonic stress wave in matrix material. The photo-elastic response of optical fiber and the birefringence induced phase change are analyzed. The relationship between fiber optic sensor phase change and the ultrasonic wave in the matrix is established. © 2005 Springer.
