Chapter 17. Fiber Optics in Sensor Instrumentation
Fiber optic instrumentation has progressively evolved since early 1980 following the successful development of optical fiber networks for telecommunications applications. To a large degree, optical fiber sensor instrumentation has taken advantage of the maturing component market for telecommunications use, and its progress has been dictated by it. Initially a significant level of research effort was put into developing sensor systems based on the use of multimoded optical fibers, but as the bias in long-haul telecommunications moved toward the use of single-moded optical fibers for improved performance, so optical fiber sensor systems began to accept the use of single-mode ...
