Nowadays it is possible to detect, without any surface preparation, delaminations, disbonds, undulations, kissing bonds, crushed core and many other types of defect.
Q-800 portable shearography system
Q-810 shearography system with on hood display
In principal the technique requires two images at two different loading conditions which are automatically compared to each other.
The small levels of loading required can be applied to the object surface using either thermal, vacuum, vibration or mechanical excitation. This creates a unique surface deformation linked to the physical response of the material to the loading.
The results are available in real-time and are displayed automatically to the operator. Further image processing can be performed to customise the results for export and reporting.
The new generation of integrated systems from Dantec Dynamics GmbH include the radically enhanced Q-810 portable shearography system typically used for Quality Assurance in production and in-field inspections.
The overall system weight has been reduced which significantly helps with day-to-day handling; the system can now easily be handled by a single person and therefore the running costs have now been reduced to a minimum.
Furthermore, a new advanced feature called “Real-time Phase Image Display” is available which provides live measurement results to the operator, allowing them to make a final judgement at an early stage.
The Q-800 and Q-810 Shearography systems are now supported by the ISTRA 4D software. This software is based on the common platform for Dantec Dynamics’ products.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
