A new approach from researchers at The Pennsylvania State University gets round these limitations by combining a compact ...

“It also needed techniques which can adapt to the diversity of materials now present in engineered structures. But, at the heart of this challenge, is the drive to find smaller and smaller defects. We ...

To answer the question of whether it is possible to put together an ultrasonic 3D imager that would cheaply enable anyone to image objects underwater, [Alec Vercruysse] and fellow team members at ...

The key breakthrough is the use of ultrasonic array sensors, which are essentially the same as those used in medical imaging in, for example, creating images of babies in the womb. However ...
