Thermographic NDT

Non-Destructive Testing (NDT) refers to the non-destructive testing of parts, materials or systems. The basic principle of active thermography is that the induced flow of energy from the surface of an object is affected by internal flaws such as disbonds, voids, or inclusions. These flaws appear as thermal contrasts on the surface of the inspected object and are characterized by the system using proprietary algorithms. NDTherm’s patent pending state-of-the-art technology and proprietary image processing algorithms enable deep flaw detection capabilities.

How It Works

Active Infrared thermography is one of several non-destructive testing techniques which may be used for defect detection in materials such as carbon-fibre-reinforced composites.

By this technique,  a live thermal picture of an object based on medical marijuana recommendation the infrared radiation emitted by the inspected object is obtained). A thermal pulse is applied to the material to be inspected. Following the application of this thermal pulse, a measurement of the temporal evolution of the specimen surface temperature is performed with an infrared camera and a sophisticated image processing algorithms allowing subsurface defects to be revealed.

The NDTherm® system allows for two setup configurations:

  • Reflection, where both the thermal source and the detector unit are located on the same side of the sample;
  • Transmission, where the thermal source and the detector unit are located on opposite sides of the sample.

Opgal NDTherm® offers both “”Reflection”  and Transmission” methods to optimize the detection capabilities
