Abstract
Active lnfrared Thermography techniques are based in detecting thermal waves previously induced in a material. This thermal waves wi ll travel through the material and carry with them information of the interna! structure of the material. Measuring the surface temperature allows to obtain that information . In infrared thermography the surface temperature is meas u red by means of an infrared camera. During the last years these techniques have had a great development because they are very fast techniques , because no contact to the material is needed and because they can be classified as non-destructive techniques. In this work, we will see some examples of active infrared thermography such as pulsed infrared thermography, modulated infrared thermography and vibrothermography.
