A local defect resonance for linear and nonlinear ultrasonic thermography [PDF]
An efficient wave-defect interaction is the key to a high thermal response of flaws in ultrasonic thermography. To selectively enhance defect vibrations a concept of local defect resonance is developed and applied to ultrasonic activation of defects ...

Effective compression algorithms for pulsed thermography data
S.201-218Two compression algorithms for the image sequences generated by pulsed-transient thermography for non-destructive testing were developed. The first algorithm allows to balance the quality of the original measurement data reproduction against a ...

Monitoring changes in skin temperature associated with exercise in horses on a water treadmill by use of infrared thermography [PDF]
Infrared thermography (IRT) was used to assess surface temperature change as an indirect measure of muscle activity and exercise associated changes in blood flow in the working hind limb muscles of horses (n¼7) undergoing water tread mill exercise. Three
