SC709: Optical Fiber Sensing Technology for Structural Health Monitoring & Smart Structures

This course is divided into two parts. Part I provides a broad overview of optical fiber sensing principles and the associated components required for system integration. Emphasis is placed on reviewing the various sensor types and their use on practical applications. In Part II, a review of strain & stress measurement using optical fiber sensors-- such as fiber Bragg gratings—is made, along with discussions on sensor placement & installation, data analysis and interpretation, design considerations and operational principles of Structural Health Monitoring (SHM). To reinforce the theoretical concepts and illustrate the practical aspects of the technology, a number of hands-on demonstrations of fiber-instrumented models and structural elements will be available.
