Exhibits of the 18th Special Show »Non-Contact Measurement Technology«

The Special Show »Non-Contact Measurement Technology« at the leading international trade fair for quality assurance »Control« in Stuttgart, April 23rd to 26th, 2024, will be held for the 18th time this year and will present the latest developments and pioneering technologies from the field of non-contact measuring and testing technology. The Special Show has established itself as a marketplace of innovations for both exhibitors and trade fair visitors and will be on display in a centrally located position in Hall 8 this year.

Concepts and goals

The Special Show, whose concept it is to present a variety of different technologies for non-contact and non-destructive measuring and testing technology in a concentrated area, offers interested parties and potential users initial guidance when selecting a suitable technology in order to master their own testing tasks. This is because the performance and flexibility of modern systems is constantly growing. Wider and wider scales are being covered and new fields of application explored. Due to the rapid pace of technical development, it is not easy for users to orient themselves on the market and make a suitable selection with regard to their own requirements. In addition to this initial orientation aid, the exhibitors at the Special Show booth also offer complete non-contact measuring and testing systems, where visitors with specific tasks can find possible solutions. The Special Show is being organized with the support of the Fraunhofer Business Unit Vision and P. E. Schall GmbH & Co. KG.

The following topics will be presented:

Thermal stress analysis with thermography

The Dresden-based company InfraTec GmbH Infrarotsensorik und Messtechnik illustrates the correlation between elastic deformation and thermal signals using the »ImageIR® 9400« thermal imaging camera and a part of a car bumper that is exposed to a periodically changing force. Thanks to this correlation, the thermal behavior and thus the internal stress of a test object can be analyzed. In the field of material and component testing, materials such as metals, plastics and composites as well as electronic power components can be examined in detail this way.

Simultaneous microscopic 2D and 3D quality control for inspecting the smallest structures

The AIT Austrian Institute of Technology from Vienna presents »ici:microscopy«, a system for simultaneous microscopic 2D and 3D quality control. The inline 3D microscope delivers up to 40 million 3D points per second and therefore enables larger areas to be scanned quickly as well. It is designed to inspect the smallest structures even at high speeds and is based on the »Inline Computational Imaging (ICI)« technology developed at AIT. This combines the methods of light field and photometry by using the natural transport motion of the object for simultaneous detection from different viewing and illumination directions. Possible areas of application include electronics production, the inspection of metallic surfaces and packaging and security print.

Wide range of training and further education in the field of industrial image processing

Industrial image processing and optical measurement and inspection technologies are an important element in the implementation of zero-defect concepts, which aim to achieve 100 percent inspection in production. Due to their non-contact, fast and reliable operation, they can now increasingly be used in step with the production cycle. However, it is still not easy for potential users to decide which image processing technology is most suitable for their own applications. The on-demand video seminars, on-site practical seminars, technology days and publications from the Fraunhofer Business Unit Vision offer a decision-making aid for this.
