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.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
Broadband rotational spectroscopy unravels structural reshaping of isolated molecules in the gas phase to accommodate water

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
