vibrometer

[vī′bräm·əd·ər]
(engineering)
An instrument designed to measure the amplitude of a vibration. Also known as vibration meter.

vibration meter

An instrument that measures the amplitude of vibration. Normally, it measures the vibration that occurs at the engine's outer casing, but it is not restricted to measuring it only. Also known as a vibrometer.

In summary, the 3D vibrometer is capable of measuring the vibration of the 3D structures including full vehicles accurately even in the high frequency range.
K](t) is determined at each of these measuring points by using the laser Doppler vibrometer and logged synchronous with the actual position signal from the encoder system of the servomotor [a.
The laser vibrometer without the accelerometer attached captures two fundamental vibrational modes with peak values at 1105 Hz and 1722 Hz.
The information from the vibrometer is stored until the X-ray scanner analyses the board, at which point the results from the two data sources are linked and the vibration information is used with the other indicating properties to predict strength and stiffness.

Vibration velocities were measured by a microscanning laser Doppler vibrometer (Polytec PSV-300-F; Waldbronn, Germany) with an OFV-056 scanning head, fitted with a close-up attachment.
The first step in the procedure is an analogue of classical linear TR for elastic waves [8]: by measuring the response signals arriving from a single or different sources using a laser vibrometer at a fixed point and returning the received signals from the original transducers in time-reversed mode, a high level of energy can be focused locally in time and space on the surface.
2] reflective film, weighing approximately 50 [micro]g, was then placed on the posterior surface of the umbo for the secondary axis vibration measurement by using a laser Doppler vibrometer (LDV).
A POLYTEC PSV-400-B Scanning Laser Vibrometer measured the natural frequencies of the test panels.
It also offers the values program (live data readings), as well as digital belt and sheave alignment and a vibrometer program for overall vibration level and bearing condition.
nysaefoliella larvae were taken under controlled conditions (enclosed room, ~23 C) by a laser-vibrometer (Polytec Compact Laser Vibrometer CLV 1000 with a CLV M030 decoder module, at a sensitivity of 25 mm [s.
