Application of Scan Laser Heating for Thermal Imagery Nondestructive Testing
Abstract
Evaluations were made using an infrared non-destructive testing technique employing scan laser heating of the specimen. Thermal images were obtained with a newly developed two-dimensional reflective scanner, coupled to a 50 watt CO2 laser to irradiate the specimen and a thermal imaging camera to view the specimen's irradiated surfaces. The technique showed a capability of providing a real time non-destructive test for subsurface defects in a variety of materials and structures. It allows the laser heat source and infrared camera to be remotely positioned from the specimen under test, making it possible to examine large specimens.
