InfraRed Image Correlation for Non-destructive Testing and Evaluation

摘要

InfraRed Thermography (1RT) is one of the widely used Non-destructive Testing and Evaluation (NDT&E) method for characterization of fiber reinforced polymers. Among various testing methodologies and associated post processing schemes, recently proposed pulse compression favorable thermal wave imaging methodologies gained importance due to their enhanced test sensitivity and resolution for identifying the sub-surface defects. The present paper highlights a highly depth resolved pulse compression favorable thermal wave imaging methodology for identification of subsurface defects in a Glass Fiber Reinforced Polymer (GFRP) test specimen.
