Abstract
Optical fiber sensors promise to play a large role in the development of smart structures which have the ability to continuously monitor themselves for internal and external structural deformation, and even actively change shape. This investigation studies one such sensor based on a fiber optic Fabry-Perot interferometer, which detects the displacement between two points of a material. Sensor theory and construction are discussed, and the tools used to analyze sensor output are developed. The interferometer is then tested by attaching it to a large cantilever beam which is deflected to produce strain. This experimental data is then used to determine Fabry-Perot cavity performance, to predict sensor accuracy and resolution, and to develop a method for relating material strain to sensor output.
