Abstract
A novel low-cost fiber optic sensor system for measuring strain in structures has been developed. The system uses low-cost digital electronics and a broad band light emitting diode (LED) to monitor low-attenuation fiber-optic strain gages. This paper introduces this new system. The architecture of the system is discussed, with details of the fiber optic strain sensing elements, the low-cost electronics, and the personal computer (PC) interface to the system. The tradeoffs which allow the low-cost system to be feasible are discussed. The laboratory experiments used to verify system performance are then presented. Finally, a description of a full-scale, outdoor application for monitoring the strain on the surface of a composite pipe segment is described.
