Description

One aspect of providing more accurate quantitative thermal inspection systems is the characterization of the lamp heat source. By measuring the heat source temporal profile, the lamp response can then be removed from the measurement for more accurate results. In measuring thermal diffusivity, Parker measured the irradiance history of a flash lamp at discrete wavelengths and approximated the energy of the pulse as a triangle [1]. Recently, this has become of more interest since advances in infrared cameras have now allowed for much higher sampling rates allowing for inspection of very fast transient temperature events. These events can potentially be influenced by the thermal heat flux temporal profile.
