Abstract

Multiplexed and distributed sensor systems are generally employed when the number of sensing points makes the use of an individually addressed sensor array prohibitive based upon some system cost function. Fiber optic sensing techniques offer great potential for the creation of multiplexed, quasi-distributed and distributed sensor systems. In addition, fiber optic sensors can be spatially weighted and configured for maximum sensitivity to particular patterns of extended parameter fields. This allows such sensors to perform a patten recognition preprocessing function, reducing system cost and processing overhead. In this paper, the appropriate use of multiplexed sensor systems, distributed sensor systems and long gauge length sensor systems with pattern matching capability are discussed as a function of system size and purpose. Design options for long gauge length sensors in terms of preprocessing functionality also are discussed. Finally, a specific example of the use of a spatially weighted sensor for vehicle identification is covered.
