Abstract

Fiber grating sensors and the Sagnac interferometer can be used to support a wide variety of high speed measurement applications. This paper explores the uses of both of these types of fiber optic sensors to measure environmental phenomenon at high speeds. In both cases there are environmental measurements that can be made at speeds that are limited only by the speed of the output detectors. In others the limitation is the response of the optical fiber itself. A series of examples will be given that illustrate the historical usage and future utility of these sensors to operate at speeds and in environments that would be very difficult for electrical sensors to match.
