Advances in sapphire-fiber-based intrinsic interferometric sensors
Abstract
We present recent advances in the development of a sapphire-fiber-based interferometric sensor. The dependence of the fringe contrast of the sensor output on the quality of the silica-to-sapphire fiber splice is investigated. Sensor performance has been improved by optimizing both the sensor geometry and its method of fabrication. This sensor was demonstrated for the measurement temperature above 1510 C, and a resolution of 0.1 C has been obtained.
