Automated photothermal tomography

Modern composite materials, such as carbon fiber-reinforced plastics, are increasingly being used in the aerospace industry due to their low weight and outstanding mechanical properties. Non-destructive testing (NDT) is essential for assessing the quality of such safety-relevant components. Based on active thermography, photothermal tomography is a fast, large-area and non-contact testing method for detecting the position and size of internal material and structural defects.

As an integrator, Fill cooperates with voidsy gmbh from Wels. The Austrian company integrates state-of-the-art thermography integration options deep into the FILL STUDIO control environment.

The concept

In addition to ultrasonic testing, the method of active thermography represents a fast and non-contact alternative to non-destructive testing. With the voidsy 3D V-ROX, the first photothermal tomography system, material and component defects can be detected and visualized over a large area.

The smart and compact NDT system developed by voidsy gmbh allows the multi-modality approach for automated inspection systems from Fill to be extended to include the method of active thermography.

The 3D V-ROX system makes it possible to obtain quick and revealing information about the damage condition of the component to be inspected prior to a detailed ultrasonic inspection.


  • Contactless and non-destructive – based on active thermography
  • Determination of absolute defect sizes
  • Reduction of inspection & evaluation time – due to innovative postprocessing
  • Significant cost reduction for quality assurance – 70% more cost-effective than state-of-the-art inspection
