Computed tomography

The two major application areas of 3D X-ray computed tomography (XCT) in science and industry are material characterization and dimensional measurements (metrology).

Synchrotron Tomography

Synchrotron X-Ray Computer Tomography (s-XCT) is very similar to the XCT measurement system. However in s-XCT a different x-ray source is used - synchrotron radiation.

Optoacoustics with Laser-Ultrasound

Conventional ultrasound measurements hold the drawback that the sample has to be in direct contact with the measurement apparatus (e.g. water jet, coupling agent). In Laser-Ultrasound the ultrasonic wave is transmitted via light.

Photoacoustic Imaging

Photoacoustic imaging is a new upcoming method combines the advantages of optical imaging (high contrast) and ultrasonic imaging (high spatial resolution). This results in various new applications in the field of biology, medicine, industry and material science.

Terahertz Technologie

The frequency range of Terahertz (THz) radiation, located between the Microwaves and the Infrared region of the electro-magnetic spectrum has become accessible in an efficient way only within the last few years. Thus, THz-Technology is an area of research with immediate actuality.

In-situ methods

Since NDT methods are non-destructive, they are predestined for in-situ investigations since the process or reaction taking place can be monitored without affecting the sample.

Active Thermography

Active thermography is based on the evaluation of a previously excited heat flow in the tested component and its disturbance by hidden defects.

Thermal Emissivity Imaging

Thermal Emissivity Imaging is a new thermographic method for the characterization of (semitransparent) thin films based on the analysis of thermal radiation (emissivity) by means of infrared or near‐infrared imaging (i.e. standard CCD cameras for temperatures above 400°C).
