Microwave induced time-resolved infrared radiometry for subsurface defect detection and characterization

Abstract
The use of microwaves as a heating source in time-resolved infrared radiometry provides the ability to heat surface and subsurface microwave-absorbing regions of a specimen directly. This can improve the contrast and spatial resolution of such regions and enhance their detectability when compared with conventional laser or flash lamp sources. Applications such as subsurface water detection or the detection of carbon fiber contaminates in epoxy composites are investigated experimentally and analytically.
