Abstract: A nondestructive system and method for high resolution thermal imaging in metal casting applications is provided to detect defects and starts with the article under test being subjected to a thermal gradient, followed by infrared images taken thereof. The creation of the thermal gradient results in any defects reacting differently to the thermal gradient application to accentuate the defect in the infrared image. The apparatus for conducting the tests in one embodiment includes a single channel sensor, remote cable, and a laptop controller with real time image processing software. This hardware provides high resolution, real-time viewable infrared (IR) images with a variable focus distance adjustable from six inches to infinity. The apparatus enables crisp, clear imagery of various metal casting defects.

Abstract: An apparatus for three-dimensional thermal imaging in medical applications, said apparatus comprising a power supply, user interface controls, focal plane array (FPA), electronics, and optics. It provides two real-time viewable IR channels for binocular vision with a variable focus distance which can be optimized at any distance from six inches to infinity. The present invention enables 3-D vision in the thermal band for greater awareness of everything within the field of view. Potential medical applications are discussed and presented.
