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

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

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
