The interferometric optical fiber sensor is classified into Michelson, Mach–Zehnder, Fabry–Perot, and Sagnac types. Fabry–Perot interferometric optical fiber sensor senses the external parameters through the change of optical cavity length. It gains popularity among domestic and overseas researchers because of advantages such as flexible design, high space resolution, small scale, and high sensitivity, especially in the structural health monitoring field. This chapter mainly introduces the white light interferometric F-P sensor and the acceleration sensor based on F-P cavity, and deeply studies the working principle, structural design, manufacturing process, and performance of the sensor as well as the software and hardware design of the signal acquisition system.
