Description: This book is the first to address the field of structurally integrated fiber optic sensors. Fiber optic sensors embedded within materials and systems are able to measure a variety of parameters (i.e.
temperature, vibration, deformation, strain, etc.) that allows for real time non-destructive evaluation. A.-D. Nguyen, V. Godinez, in Corrosion Control in the Aerospace Industry, Fiber optic sensor for health monitoring.
Optical fiber sensors can be incorporated into structures to provide health monitoring, providing strain, temperature, acoustic emission, and ultrasonic wave information indicating when crack and corrosion occur and where.
This paper reviews the operating principles, sensor types, benefits and applications of optical fiber sensors for non-destructive testing of materials and structures in different fields such as.
The fiber Fabry–Perot sensor (Kist et al., ; Lee and Taylor, ) is a useful sensing device because it is an inline sensing element (see Figure ).It is essentially an optical cavity that is defined by two semireflecting parallel mirrors (see Figure ).More usually, the Fabry–Perot cavity (at least in bulk optic form) has highly reflecting mirrors of reflectivity R such that.
The resistance and stiffness of these materials are directly related to their fiber orientation. Thus, efficient approaches to assess their fiber orientation are in demand.
In this paper, a non-destructive evaluation method is applied to assess the fiber orientation on laminates reinforced with randomly-oriented strands.

The field variations, for simplicity reasons, were assumed mechanical only, decoupled from any thermal effect, by keeping the environmental conditions stable during the experimental study. Both methods allow the visualization of the internal structure and hence allow identification of the type and the extent of damage.
