ADVANCES IN NON-CONTACT THERMAL-WAVE IMAGING WITH INFRARED DETECTION.
Abstract
We are making further advances in non-destructive and non-contact thermal imaging with infrared detection. We employ a chopped and scanned electron beam as heat source, a cooled HgCdTe infrared detector as temperature sensor, and digital processing of the measured temperature pattern for display and storage. The results give a convincing, high contrast image of subsurface structures.
