Abstract
A dual wavelength fiber optic monitoring system utilizes the principle of conservation of throughput to permit the use of a plurality of transducers illuminated by a single source unit. Redundancy is provided by using a plurality of sources and detector units and by the use of optical couplers to transmit the light beams between these elements.
