ABSTRACT:
A method for processing thermography signals. A time series of radiometric data is measured from a surface (104) of an object (102) over a period of heating and subsequent cooling, and a mathematical curve (1, 2) is fit to the data. An amplitude aspect and one or more shape aspects are identified for each curve. The amplitude and shape aspects are then used together to characterize features such as defects in the object. The amplitude and shape aspects for an array of such data may be combined in a single noise-free visual display (100) by associating hue (color) with the shape aspect and luminance (brightness) with the amplitude aspect. Optionally, a second shape aspect may be identified and associated with saturation on the display. A visible image of the object may be overlaid on the display.
