IR NDT systems: optical lock-in thermography

Infrared thermography can also be used in optical lock-in mode for non destructive testing. Optical lock-in thermography is well suited for deeper default inspection. See the Thermography Tutorial on the left for more information on lock-in thermography.

A lock-in thermography setup typically includes:

- 1 or more heaters, IR lamps or projectors
- 1 support for the heaters
- 1 controller to adjust the signal of the heater
- 1 acquisition station (PC)
- 1 infrared camera

Components are carefully selected depending on your needs. Visiooimage engineers help you selecting the right components with the right specifications and ensure that the bench setup will work with the materials to be tested.
