Fiber grating environmental sensing system
Abstract
A fiber grating environmental sensing system is described that has the ability to measure strain, vibration, humidity and water content. Fiber gratings are used to measure axial strain to accomplish these goals. An approach is described that uses matched fiber grating sensors and filters to allow for thermal compensation greatly reducing one of the key performance issues facing these systems. The system may be deployed in such applications as roadways and paved surfaces, bridges, buildings and aircraft and spacecraft. Means are described to implement transducers optimized for specific environmental measurements as well as means to demodulate the fiber grating sensors.
