Usage of Multi-Axis Fiber Grating Strain Sensors to Support Nondestructive Evaluation of Composite Parts and Adhesive Bond Lines

Abstract

By writing fiber gratings into birefringence polarization preserving optical fiber two and three dimensional strain may be measured. It has been demonstrated that these multi-axis fiber grating strain sensors may be used to measure shear strain and transverse strain gradients. This paper will overview the usage of these sensors to perform nondestructive evaluation of adhesive joints and composite parts.
