Acoustic waves play many everyday roles – from communication between people to ultrasound imaging. Now the highest frequency acoustic waves in materials, with nearly atomic-scale wavelengths, promise to be useful probes of nanostructures such as LED lights.
However, detecting them isn’t so easy.

Non-destructive testing is a descriptive term used for the examination of materials and components to determine surface and subsurface defects in a way that allows such materials to be examined without changing or destroying their original design or structure.
NDT plays a crucial role in everyday life and is necessary to assure safety and reliability. Typical examples are found in aircraft, motor vehicles, pipelines, vessels, bridges, trains, power stations, refineries and oil platforms which are all inspected using NDT.
NDT is also a quality assurance production and management tool which can give impressive results when used correctly. It requires an understanding of the various methods available, their capabilities and limitations, knowledge of the relevant standards and specifications for performing the tests.
