Abstract : Innovative computational analysis methods and image processing techniques were combined with a commercially available infrared (IR) thermal imaging video system to produce complete surface thermographic data of a ramjet combustor configuration. The components of the data analysis system, the data-reduction procedures, and typical test data are presented. Data precision and the limitations of the infrared system are discussed. Unique capabilities of the system included continuous infrared color or gray-scale video monitoring of a heated test article,full-frame video digitizing and image enhancement of infrared thermal images, and computer processing to produce complete surface 3-dimensional thermal topographic data plots of a heated combustor under actual operating conditions. Thermographic analysis, Infrared thermal imaging, Video digitizing, Image enhancement. (mjm)
