In this paper, we describe the use of optical frequency domain reflectometry for high-spatial resolution strain measurements to address some mechanical and geotechnical applications. The basic principles of optical frequency domain reflectometry are illustrated, and examples of its application to the measurement of strain in open-hole specimen testing, a physical geotechnical model, and foundation piles are examined and discussed.
