Abstract

Optical fiber sensors can be used to monitor many parameters such as strain on modern high-temperature alloys during cyclic loading and pressure in composite manufacturing processes. Presented are the application and operation of several fiber optic sensors based on the extrinsic Fabry- Perot interferometer technique. The results from strain measurements demonstrated that the fiber optic strain sensors are able to withstand extreme temperature [ambient to 2070 degree(s)F (1132 degree(s)C)] while maintaining a high level of performance. The capabilities of the fiber optic sensors make it possible to monitor many material property changes and measureands.
