Interaction Model for a Hi-Bi Fiber Optic Ultrasonic Sensor and the Host Material
Source abstract
Abstract
A dynamic model of an optical fiber segment with polymer coating, which is embedded in concrete, is proposed for evaluating the response of the ultrasonic stress wave in the host material (matrix). The photo-elastic response in the optical fiber and the associated birefringence-induced phase changes are analyzed. The relationship between fiber optic sensor phase change and the ultrasonic wave behavior in the matrix is established.
