Fiber Optic Sensors In Structural Health Monitoring

Three fiber optic sensors for structural health monitoring.

Fiber optic sensors in structural health monitoring.

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. Fiber optic sensor technology is being developed to provide existing and future aircrafts with shm capability due to its unique superior characteristics. The following provides a brief review to the most widely used shm sensors for structural monitoring. Development of fiber optic methods for shm based on short gauge longgauge and distributed sensors can be found in the following books.

Fiber optic sensing allows for highly accurate robust and continuous structural health monitoring predicting and preventing equipment failure and structural damage to infrastructure. This paper presents an overview of hybrid fiber optic sensing systems based on scattering techniques fiber bragg gratings interferometric techniques and polarimetric methods in structural health monitoring. 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.

Wiley new york ny usa. This special issue will focus on the current state of the art of optical sensors for structural health monitoring shm covering recent technological improvements in new devices sensors and emerging applications. Both original research papers and review articles describing the current state of the art in this research field are welcome. The first fiber optic sensor a closed loop fiber gyro was invented to replace mechanical spinning gyros on the delta rocket in 1978.

Conception of such foss originated from fiber optic communications. Fiber optic sensors in structural health monitoring abstract. The latest advances in research on sensor technology for structural health monitoring has been resulted in various types of shm sensors. Structural health monitoring shm based on advanced sensor technology is potentially a cost effective approach to meet operational requirements and to reduce maintenance costs.
