Fiber optic sensors in structural health monitoring.

Fiber optic sensor technology is being developed to provide existing and future aircrafts with shm capability due to its unique superior characteristics. Fibre optic methods for structural health monitoring john wiley sons inc. Unaffected by electro magnetic fields and resistant to extreme temperatures and stress fiber optic sensors can be used even in the most harsh environments. The use of an online monitoring system based on brillouin optical time.

Smart structural health monitoring of composite materials with optical fiber sensors is becoming more and more important especially in the aviation industry. An introduction for engineers and scientists. The first fiber optic sensor a closed loop fiber gyro was invented to replace mechanical spinning gyros on the delta rocket in 1978. The following provides a brief review to the most widely used shm sensors for structural monitoring.

Three fiber optic sensors for structural health monitoring. Structural health monitoring shm based on advanced sensor technology is potentially a cost effective approach to meet operational requirements and to reduce maintenance costs. Nowadays optical fiber sensors are widely used in different structural health monitoring systems 46 47 48 49 50 51. Fiber optic sensors in structural health monitoring abstract.

Wiley new york ny usa. Fiber optic sensing allows for highly accurate robust and continuous structural health monitoring predicting and preventing equipment failure and structural damage to infrastructure. Development of fiber optic methods for shm based on short gauge longgauge and distributed sensors can be found in the following books. Structural health monitoring shm can be understood as the integration of sensing and intelligence to enable the structure loading and damage provoking conditions to be recorded analyzed localized and predicted in such a way that nondestructive testing becomes an integral part of.
