Digital Imaging Suite for Nondestructive Evaluation of Materials

Abstract

The University of Dayton Research Institute has acquired a digital imaging suite suitable for acquiring images in the visible and mid-infrared wavelengths. The primary equipment in the suite, for infrared imaging, is an Indigo Systems Phoenix camera, with 256 x 320 pixel images. It is sensitive to energy in the 3-5 mm band and has a resolution of 25 mK and a 14-bit dynamic range. A variety of lenses, image processing software, and a flashlamp thermal excitation system are used with the camera for a wide variety of active and passive thermographic nondestructive evaluation (NDE). NDE applications include inspection of composite materials, temperature field mapping, examination of test specimen self-heating, and others. A 3M pixel digital camera and an Infinivar infinitely focusable telescope/microscope lens are used for visual wavelength imaging with the suite.
