Fiber optic sensors in 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. 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. Three fiber optic sensors for structural health monitoring. The following provides a brief review to the most widely used shm sensors for structural 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.
