A laser Doppler vibrometer (LDV) is a scientific instrument that is used to make non-contact vibration measurements of a surface. The laser beam from the LDV is directed at the surface of interest, and the vibration amplitude and frequency are extracted from the Doppler shift of the reflected laser beam frequency due to the motion of the surface.
The scanning laser vibrometer or scanning laser Doppler vibrometer, was first developed by the British loudspeaker company, Celestion, around 1979, [1] further developed in the 1980s, [2] and commercially introduced by Ometron, Ltd around 1986. It is an instrument for rapid non-contact measurement and imaging of vibration.
Laser Doppler velocimetry, also known as laser Doppler anemometry, is the technique of using the Doppler shift in a laser beam to measure the velocity in transparent or semi-transparent fluid flows or the linear or vibratory motion of opaque, reflecting surfaces. The measurement with laser Doppler anemometry is absolute and linear with velocity ...
Continuous-scan laser Doppler vibrometry (CSLDV) is a method of using a laser Doppler vibrometer (LDV) in which the laser beam is swept across the surface of a test subject to capture the motion of a surface at many points simultaneously.
[8]: 25 He was the first to transistorize the design and make it commercially practical as a means to measure machine vibration and thrust position protection systems in rotating machinery. [ 1 ] In the company's early years, its non-contacting displacement sensors were used primarily by manufacturers in their laboratories rather than in ...
Maude. This waterproof, 4.8-inch vibrator has three speeds that are easy to operate with a touch button at the base. It's designed for external and internal use, and comes with a discreet little ...
