Fractal Analysis Applied to Laser Spot Thermography
Publication: Publication Date: 1 March 2016Testing Method:
In the study presented in this paper, fractal
analysis was applied to raw infrared images
relative to the nondestructive testing technique of
laser spot thermography. Laser pulses were used
to impart heat to a composite laminate containing
artificial discontinuities. The temperature distribution
produced by this thermoelastic excitation was
measured with an infrared camera and processed
with an algorithm based on fractal analysis. The
experimental results were interpreted and
compared to simulated images and it was found
that the algorithm enabled the detection of
damage but was unable to quantify the size of the
