Investigation of a Laser Illuminator - Thermal Imaging System for the Detection of Voids and Disbonds

Abstract

An infrared nondestructive testing technique employing laser heating of the specimen was developed and evaluated on several bonded materials. Thermal images were obtained using a two-dimensional reflective scanner coupled to a 30- watt CO2 laser to irradiate the specimen and a thermal imaging camera to view the specimens irradiated surface. The technique is capable of providing a versatile, high-resolution, real-time non-destructive test for subsurface defects in large specimens.
