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 ...

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 ...

MetroLaser is pleased to introduce the VibroMet 500 SLDV, the first truly portable scanning laser Doppler vibrometer. The vibrometer enables a user to perform a ...

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 ...

Today, a vast number of micro-manufactured sensors, actuators and components vibrate at frequencies in the high MHz range. Some examples of these high-frequency vibrating systems include surface ...

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 ...

Laser measurement can calibrate a precision microphone as well as traditional techniques, according to the US National Institute of Standards and Technology (NIST). Such calibration is required in ...
