Analysis Methods of IRBIS® 3 active
The heat flow of the test object will be analysed by means of incline or decline of the surface temperature.
Pulse Phase Thermography (PPT)
The temperature curve will be analysed depending on different frequencies (n = 1, 2, 3 ...). One amplitude image and one phase image will be established for each frequency.
Lock-in Thermography (LIT)
The sequences of periodical excitation of the test object will be analysed.
