1. A method for detecting flaws comprising the steps of: heating a portion of a surface of an object wherein the surface is defined by a plurality of individual surface elements; recording a plurality of thermal images of the portion over time with a thermal imaging device wherein each of the plurality of thermal images being defined by a plurality of pixels and wherein each of the plurality of pixels having an individual pixel address and corresponding to one of the plurality of individual surface elements; determining a pixel intensity for each of the plurality pixels in each of the plurality of thermal images; integrating the pixel intensity of each of the plurality of pixels having the same individual address from respective thermal images to establish elements within an array of integrated pixel intensity; and using the array of integrated pixel intensity to detect a flaw in the object.
