MetroLaser Custom Product The
VibroMet™ Long Range Laser Doppler Vibrometer The Long
Range Laser Doppler Vibrometer (LR-LDV) has many of the same applications
as the VibroMet 500, however it can be used at much farther distances
- up to 50+ meters! The LR-LDV
may be used for a variety of applications in the automotive industry including
measuring brake pad and tire noise and testing turbo chargers and exhausts.
The LR-LDV can be used for seismic exploration and monitoring. Here the LR-LDV is pointing at a building column while the computer monitor displays the vibration signature of the column.
The picture above shows what the you might expect from our software. The top trace is the “vibration velocity vs. time” signal. The bottom trace is a spectrum of the velocity vs. time signal and it shows the frequencies of the signal. In this particular example there is only one frequency (single tone) of about 2 kHz. The panel to the right displays key properties important in characterizing and analyzing vibration. |
