A way of monitoring household appliances by using machine learning to analyse vibrations on a wall or ceiling has been developed by researchers in the US. Their system could be used to create ...

Laser vibrometry is used for research and diagnostics on the inner and middle ear. Vibrometers have also been used for measuring vibration on artificial heart valves to analyze vibrations during ...

The fundamental way to develop the next generation of resonant-based sensor technology is via the characterization of the motion of high-frequency microdevices with sub-nanometer resolution.

Laser Doppler vibrometers (LDVs) measure vibrations in ways that other sensors can't. From large aircraft structures to microscopic MEMS sensors, and vacuum enclosures to red-hot mills, LDVs measure ...

The use of high-speed cameras permits to visualize, analyze or study physical phenomena at both their time and spatial scales. Mixing high-speed imaging with coherent imaging allows recording and ...

The Polytec Inc. PSV-400-3D scanning laser vibrometer, utilized in experimental modal analysis, uses Doppler shift of back-scattered laser light to determine instantaneous velocity and displacement of ...

Electronic devices are usually thought of as securely and safely mounted in a protective enclosure or sitting on a table top, yet portable devices require completely different standards to which ...
