Paper Abstract

Recent studies have shown that the advantages of fiber optic sensors in aircraft flight control are realized at the system level, not in the sensors or components themselves. These advantages derive from a fiber-optic systems approach in which the number and variety of cables and interface circuits are reduced by optical multiplexing. This paper describes a top-down approach to sensor system design which emphasizes selection of a network architecture to maximize system-level criteria prior to specification of sensor types. A key aspect of this design is multiplexing arrays of sensors through a common electro-optical interface. The most desirable multiplexing technique and network architecture would be one which is compatible with all or at least the greatest number of sensors while reducing system size and weight. Similarly those sensor types which are compatible with optical multiplexing are more desirable than those which cannot be easily incorporated into a multiplexed network. Several candidates for multiplexing are compared on the basis of system impact.
