Materials Characterization and Testing

Non-Destructive and Contactless Measurement With Optical Techniques

We develop application-oriented measurement systems for material characterization and testing. In doing so, our scientists draw on expertise in optical system and measurement technology, spectroscopy and the development of innovative data processing techniques. The technologies range from optical coherence tomography (OCT) in the visible and near-infrared spectral range, hyperspectral imaging in the near- and mid-infrared, and time-domain spectroscopy in the terahertz frequency range to electronic system concepts in the millimeter-wave range. All of these techniques operate in a non-destructive and non-contact manner.

The technologies we use are diverse.
 

We Use:

• optical coherence tomography (OCT) in the visible and near-infrared spectral range
• hyperspectral imaging in the near and mid-infrared spectral range
• time domain spectroscopy in the terahertz frequency range
• electronic system design in the millimeter-wave range

All of these techniques operate in a non-destructive and non-contact manner.
 

Typical Material Testing Tasks are:

• Detecting internal defects in ceramics, plastics or even fiber-reinforced composites
• Determining individual layer thicknesses in multilayer systems such as coatings or multilayer components such as tubes or films
   

Material Characterization Is Often Based on Spectroscopic Tasks:

• Identifying and distinguishing materials
• Determining specific characteristics such as moisture or sugar content
   

Our Offer for Material Characterization and Testing Includes

• Technology consulting
  
• Initial tests and feasibility studies
  
• Measuring studies and measurements on customers site
  
• Development from single components up to individual complete systems
  
• Equipment rent

In the course of time, our scientists have realized different inspection systems and sensors, of which we present a small selection here.

In addition to the actual sensor technology, the customized software is an essential component of the test systems. On the one hand, it ensures optimum evaluation of the measurement data and comprehensible presentation of the results. On the other hand, it enables intuitive operation and integration into the companies' individual data infrastructure.

We develop individual solutions – from the sensor to the complete test system.
