Major 6 Oct 2006 For this reason, laser doppler vibrometry (LDV)—a noncontact approach that measures the velocity and displacement of a vibrating device—is 20 Oct 2011 Laser Doppler Vibrometry(LDV). • Other (Spectroscopy •Imaging rate slow for laser scanning (<3 fr./sec).

Single-point vibrometers are laser vibration sensors that measure object vibrations in the direction of the laser beam (out-of-plane motions). Scanning Laser Vibrometer. Optomet Scanning Laser Doppler Vibrometers (SLDV) scan the surface of a measurement object with the laser beam using a mirror deflection unit, so that a large number of measuring points can be automatically measured in a very short time. By combining the vibration data of the individual measuring points, vibrometry becomes a powerful imaging method. Single-point laser Doppler vibrometers measure transfer functions, amplitudes and resonance frequencies without contact in a non-intrusive way thanks to the simple “point and shoot” principle. Single-point vibrometers are laser vibration sensors that measure object vibrations in the direction of the laser beam (out-of-plane motions).

The principle is to shoot a small laser beam at the Laser Doppler vibrometers. Laser Doppler vibrometers from Polytec are precision vibration sensors and comprehensive optical testing solutions representing the globally established gold standard for non-contact vibration analysis.

In our Laser Vibrometer a red laser pointer beam gets reflected by a retro-reflective foil, the reflected light generates interference speckle patterns on surfaces around the laser beam, hence called “The Speckle Laser Vibrometer”.At ~1m from the reflector, the speckles are spaced 1- 3 mm. Single-point laser Doppler vibrometers measure transfer functions, amplitudes and resonance frequencies without contact in a non-intrusive way thanks to the simple “point and shoot” principle.

These shown vibrometer companies from India are known for its product durability. Background: Heartbeat detection is a crucial step in several clinical fields. Laser Doppler Vibrometer (LDV) is a promising non-contact measurement for heartbeat detection. The aim of this work is to assess whether machine learning can be used for detecting heartbeat from the carotid LDV sign … The scanning laser vibrometer or scanning laser Doppler vibrometer, was first developed by the British loudspeaker company, Celestion, around 1979, further developed in the 1980s, and commercially introduced by Ometron, Ltd around 1986.

The At series laser doppler vibrometer can measure the vibration of an object without contact, by means of the optical heterodyne method. By fm-demodulating the difference in frequency between reference and measured light, the at series can detect the speed and frequency of an object's vibration, rendering microvibration measurement possible. With its build-in stabilized SWIR laser the Optomet Dual Fiber vibrometer gets excellent signal-to-noise ratio on nearly any test surfaces. Thanks to ultraDSP, Optomet’s innovative digital signal processing technology, the vibrometer achieves highest accuracy in combination with an outstanding resolution of 1.7 nm/s for velocity and 0.05 pm for displacement.
