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. Nowadays optical fiber sensors are widely used in different structural health monitoring systems 46 47 48 49 50 51. 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.

Wiley new york ny usa. Fiber optic sensors in structural health monitoring abstract. 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 sensor technology is being developed to provide existing and future aircrafts with shm capability due to its unique superior characteristics. The latest advances in research on sensor technology for structural health monitoring has been resulted in various types of shm sensors. 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.

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. Smart structural health monitoring of composite materials with optical fiber sensors is becoming more and more important especially in the aviation industry. Structural health monitoring shm based on advanced sensor technology is potentially a cost effective approach to meet operational requirements and to reduce maintenance costs. Development of fiber optic methods for shm based on short gauge longgauge and distributed sensors can be found in the following books.
