Laser doppler vibrometer

As shown in the figure, the laser Doppler vibrometer includes a laser light source 1, a first beam splitter 2, an acoustooptic device 3, a second beam splitter 4, a photoelectric converter 5, a third beam splitter 6, a reference signal generator 7, and a mirror. 8 includes a light transmission / reception optical unit 10 and a displacement calculation device 11. The book covers both theoretical aspects and practical applications of laser Doppler vibrometry, and is accompanied by a multimedia presentation that allows the audience to browse the content and come as close as possible to performing real experiments.

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. 2008-01-01 2021-02-01 Laser Doppler Vibrometer is the most common type of laser vibrometer being used these days to measure substrate-borne vibration. However, the Doppler Laser Vibrometer is quite expensive since it utilize expensive optics.

Doppler effect - Wikipedia 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 laser Doppler vibrometer (LDV) system used for calibrating the spring constant of AFM cantilevers is housed 12 m underground in the Nanomechanical Properties Group’s clean room lab in the Advanced Measurement Laboratory (AML) at NIST. The lab affords a clean, low vibration environment with good temperature and humidity control. Digital Laser Doppler Vibrometer Nova-Series HIGH-END AND BEST-PERFORMANCE The „Nova-Series“ Laser Vibrometer operates with an invisible SWIR La-ser (1550 nm). At a wavelength of 1,550 nm, ten times the laser power of a HeNe system is available for measurements without compromising the eye safety.
