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.
Extended Benefits:• Improved image and shearography results

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
