<title>Fiber optic monitoring buses with binary on-off sensors</title>

subject

description

This paper presents general theoretical considerations of complex-structure optical fiber networks (buses) with binary `on-off' fiber optic sensors and fiber optic transmission lines for monitoring, diagnostic or measurement systems. The principles of fiber optic serial and parallel buses and various types of intensity fiber optic binary sensors are described as well as the advantages and disadvantages of the individual types of networks. The choice of the use of fiber optic technology rather than other techniques is discussed. Special emphasis was put on the role and function of optoelectronic and optical fiber devices in harsh environments. Theoretical considerations are illustrated by the examples of protection systems for large structures in chemical, electric power and civil engineering.© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
