Method and apparatus for implementing material thermal property measurement by flash thermal imaging

A system for implementing measurement of material thermal properties including measurement of thermal effusivity of a coating and/or film or a bulk material of uniform property comprising:

• an infrared camera,
• a data acquisition and processing computer coupled to the infrared camera for acquiring and processing thermal image data,
• a flash lamp providing an input of heat onto the surface of a two-layer sample;
• an optical filter covering the flash lamp for attenuating an entire infrared wavelength range of thermal images taken of the surface of a sample;
• and
• said data acquisition and processing computer performing a measurement solution to determine material thermal properties including thermal effusivity of the sample.
