Abstract

Optical fibers have an inherent capability of transmitting high bandwidth analog and digital signals. To apply this property of fiber optics to remote sensing, special sensing heads as well as signal processing electronics have to be developed. In systems employing intensity modulating sensors, there is also a need for a referencing technique to compensate for changes in the transmission of the connecting fibers and light source intensity. This paper discusses fiber optic sensing systems using intensity sensors incorporated in sensing heads of a special configuration. Different modes of operation as well as resonant conditions are explained. Theoretical and experimental analyses are also given.
