Leather Inspection – LEATHER CHECK
NDT (Non Destructive Testing) of Leather for repairs with filling compound and for inhomogeneities

Increase Speed and Your Bottom Line with Our Turn-Key Solution

• Save Time
  With Leather-Check, defects and repairs in leather can be reliably detected within short times.
• 100% Safe For Leather
  During the measurement the leather is warmed up to a short time maximum temperature of less than 40C. Damages or changes of the shape are impossible.
• Flexible Operation
  The system allows a manual as well as a fully automated inspection process.
• Clear Results
  Instead of temperatures the system measures and evaluates differences in the temporal behavior of the heat at the leather surface. Therefore the system shows defects and repairs with an excellent contrast. Measurement results are clearly reproducible and are insensitive for any external effects.
• Scalable Solution
  Variable system design, from mobile systems for manual measurements up to stationary systems with high throughput, full automatic data processing and control.

Leather-Check uses a variant of IR thermography known as “lock-in” thermography to analyze samples under test. In this method, the sample to be tested is heated at its surface by an intensity modulated source. This heat penetrates into the interior of the sample as a thermal wave and any change in the properties of the sample material such as cracks, cause a change in the propagation characteristics of the wave.

After the thermal wave is reflected to the surface of the sample, it becomes superimposed (or “locked-in”) onto the initial wave such that any defect is revealed by a local change in the phase angle. By recording the surface temperature of the sample with an IR camera, the temperature-time function of the image can be analyzed on a host computer. By calculating a phase image, the internal structure of the component and its interior defects are revealed. Depending on the modulation parameters of the heat source during the measurement, different depth ranges within the image can be displayed.
