Heat flow thermography requires inhomogeneous thermal stimulationof the test specimen. This stimulation is applied
- periodically (for lock-in thermography),
- as a delta or rectangular pulse or
- in steps.
Thermosensorik adapts and develops various thermal stimulation sources and integrates them into the infrared testing systems.
In the following PDF-document the most common stimulation sources are presensted:
- Flash lamps
- Halogen lamps
- Ultrasound
- Induction
- Hot/Cold air
- LED-arrays
- Laser
- Electrical stimulation
- Mechanical stimulation
