Laser scanning vibrometer
VibroMet™ 500 SLDV
HGL Dynamics
The system uses the patented VibroMet™ 500V engine, together with computer-controlled scanning mirrors and a comprehensive software package to quickly produce vibration maps of any surface.
The system is optimized for measuring distances from about half a meter to five meters, so there is no need for adjustments, lens accessories, or object treatment, thus ensuring the highest level of measurement accuracy.
The VibroMet™ 500 SLDV measures the velocity and frequency of vibration at up to 1000 points in the horizontal and vertical direction of a vibrating target spanning an angle of ± 20° in each direction.
There are three parameters that define the measurement requirements:
Distance to target - For good reflecting surfaces, the VibroMet™ 500 SLDV can measure targets at any distance between about 0.5 m and 5 m. If the surface is not a good reflector, then the maximum distance may be less than 5 meters.
Frequency of vibration - The VibroMet™ 500 SLDV can measure frequencies from close to DC to 40 kHz.
Velocity of vibration - This parameter has a maximum value of 0.8 m/s and may be calculated as follows: V = 2 PI * amplitude * frequency. For example, if the amplitude of vibration were 10 microns and the frequency of vibration 1 kHz, then the velocity would be 0.063 m/s.
