Optical Fiber Strain Sensors

Abstract

Fiber optic sensor (FOS) technology uses optical fibers. FOSs offers important advantages over conventional sensors, such as immunity to electromagnetic radiation, multiplexing, small size, high sensitivity, high accuracy, remote sensing, and are chemically and biologically inert. They have been employed for measurement of temperature, strain, index of refraction, humidity. Their development has been stimulated by the technological progress of fiber optic communication by providing higher performance, more reliable telecommunication links with decreasing bandwidth cost.
