Fiber Optic Sensor Network for Structural Health Monitoring

摘要

Closed meshed instrumentation or sensor networks with conventional sensors for temperature and strain emasurements may result in excessive penalties in terms of weight constraints, sensitivity to environmental conditions and complex interfaces. The FOS is a multiplexed sensor system for up to 50 single strain and temperature measurement points comprising of a fibre network and an optoelectronic unti. The FOS senosr was designed and developed by Kayser-Threde, Munich, for demanding space environment, but can also be emphasized as a promising sensor technology with high potential for nonspace applications.
