1. A fiber optic detection system comprising:
- source means for producing a light beam,coupling means for coupling said light beam into a transducer for measuring a physical parameter, andredundancy means connected to said transducer for directing light from said transducer to a plurality of optical fibers, anddetector means for receiving light from said plurality of optical fibers, the optical throughput of said detector means being at least equal to the optical throughput of said plurality of optical fibers,wherein at least one of said plurality of optical fibers traverses a physical path substantially different from that of other of said plurality of optical fibers.

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.
