2.1 Area of Application
Polytecs Portable Digital Vibrometer PDV-100 is used for non-contact
measurements of surface vibrational velocities. The PDV-100 is a compact,
portable laser vibrometer with state-of-the-art design of optics and signal
processing. The PDV-100 is shown in

In the frequency range from 0.05 Hz ... to 22 kHz the handy PDV-100 allows
you to realize measurement accuracy which you previously needed a
stationary measurement device in a calibration laboratory to achieve. With the
three measurement ranges, which cover a velocity range from 0.05 μ m / s to
0.5 m / s, and with precise digital filters you can optimally to adjust the PDV
nearly all applications in the acoustic frequency range.
