Abstract
Abstract This article provides a tutorial introduction to transportation infrastructure health monitoring using fiber optic sensors. Since the topic spans many disciplines, our goal is limited to providing a basic conceptual framework. We begin by reviewing the prerequisite topics from fiber optic sensor and structural health monitoring, including a brief review of point and distributed fiber optic sensor technologies. We then provide a comprehensive review of key fiber optic sensors which may be used in the transportation infrastructure monitoring. Point fiber optic sensors are first discussed and then distributed fiber optic sensors. Performances of each sensor are discussed based on the transportation infrastructure monitoring application. We conclude the tutorial with a number of observations on the current directions of the research field of the fiber optic sensor for the transportation infrastructure health monitoring.
