Measuring system for hyperspectral surface and layer inspection

The Fraunhofer Institute for Material and Beam Technology IWS, Dresden, introduces imanto® obsidian, a measurement system for hyperspectral surface and thin film testing. With the help of hyperspectral imaging (HSI), the light reflected from a sample to be inspected is not only recorded with spatial resolution, but also with spectral resolution. Since different surface conditions - material- or topology-related - manifest themselves in a spectral change of the optical behavior of the sample section through deviating absorption, refraction or scattering, hyperspectral imaging represents a universal tool for determining and visualizing the distribution of multiple surface and layer parameters or sample properties derived from them, and thus for clarifying industrial processes, making them more effective and automating them.

High-quality microfocus X-ray tubes for non-destructive, contactless measurement tasks in industry, research and development

Viscom AG from Hannover, Germany, shows a selection of its high-performance microfocus X-ray tubes, which cover a wide range of applications and are characterized by their compact design and long maintenance intervals. Both in x-ray laboratories and as a component of premium machines, the most diverse tasks can be solved with just one system, from the inspection of small, filigree objects with high resolutions to time-optimized series inspections and the radiography of large and massive components. In a coordinate measuring system with X-ray computed tomography for three-dimensional quality control of workpieces, it is therefore not necessary to install two different types of tubes in order to quickly set up the inspection of completely different objects via the operating software.

Portable surface particle counter with wireless measuring head

The PMT Partikel-Messtechnik GmbH from Heimsheim, Germany, will show PartSens 4.0, a portable measuring system with a wireless measuring head for direct measurement of particles on various surfaces such as stainless steel, silicon, glass or plastic. The measurement result, including the captured images, is transmitted in real time via WLAN and displayed on a screen. The PartSens+ 4.0 model additionally offers the possibility of differentiating particle sizes and numbers of metallic and non metallic particles as well as fibers on surfaces. Reproducible and accurate measurement results are generated by using the grazing light technology according to ISO 14644-9. Complex sampling by gas extraction is eliminated, as are subjective measurement methods or error-prone multi-stage procedures, such as surface rinsing through filter media with subsequent filter analysis. Applications can be found in all areas where clean product surfaces or production environments must be ensured.

Software platform for augmented reality based quality control

With »Twyn«, Visometry GmbH, Darmstadt, presents a mobile, flexible and fast software platform for the quality inspection of components and assemblies. With the help of a tablet's camera, the software automatically locates, registers and tracks the test parts. Using CAD data and augmented reality (AR), a digital twin is superimposed directly onto the object - no special markings or other preparation of the test item is required for this. Deviations between target and actual conditions thus become directly visible to the inspector. The system can be used, for example, to determine the geometric deviation, to check the alignment and position of a component or to check for completeness.

Automotive platform for mobile data acquisition

The Institute for Information and Communication Technologies DIGITAL of the Joanneum Research Forschungsgesellschaft mbH from Graz (Austria) shows a flexible, vehicle-mounted outdoor sensor system for georeferenced recording of static and dynamic objects.

In the sensor network, data from GNSS / IMU (Global Navigation Satellite System/Inertial Measurement Unit), LiDAR, radar and high-resolution cameras are recorded synchronized and geo-referenced and made available as a data source. The weather-protected and inconspicuous design enables 360-degree acquisition around the own vehicle and provides automated data for subsequent simulation and evaluation tasks. One possible field of application is, for example, the examination of road surfaces on highways and freeways in order to detect potential road damage (small cracks, incipient ruts or potholes) and other irregularities at an early stage. With the help of the system, detailed road wear maps are created that contain the impairments and the associated safety risks down to the centimeter.

Initial and continuing education offers in the field of industrial image processing

Machine vision and optical measurement and inspection technologies are an important element in the implementation of zero-defect concepts whose goal is 100 percent inspection in production. Their contactless, fast and reliable operation means that they can now be used increasingly frequently in step with the production cycle. However, it is still not easy for potential users to decide which machine vision technology is most suitable for their own applications. The Technology Days, seminars and publications of the Fraunhofer Vision Business Unit offer decision support for this purpose.
