Optical-fiber sensors

The primary aim of this issue of MRS Bulletin is to present an overview of the deployment of optical-fiber sensors in a selected range of applications. The topics covered include a general introduction to optical fibers; a review of the sensing mechanisms that are available to monitor strain, temperature, pressure, chemical species, damage, and acoustic emission; and the use of optical-fiber sensors in medical applications. This introductory article presents a brief discussion of the advantages and disadvantages of optical-fiber sensors.
