Synchronous optical vibrometry with up to 48 channels

With the laser-based MPV-800 Multipoint Vibrometer from Polytec, you can carry out time-synchronous measurements with up to 48 channels and represent both frequency-dependent and time-dependent deflection shapes. The fiber-optic sensor heads are freely configurable and allow you to perform flexible measurements – both parallel to a surface or arranged individually around the sample you’re using to record all the measurement values.

Highlights

  • Non-contact and reactionless vibration sensing
  • Capture transient and non-stationary events in a single synchronous measurement
  • Flexible and user-configurable up to 48 optical channels
  • Time- and frequency resolved deflection shapes in 3D
  • Non-contact vibration measurement
  • Best optical sensitivity avoids surface preparation
  • Eye-safe laser

Perfectly capture the defining moment

You can use the multipoint vibrometer to analyze time-critical phenomena with maximum resolution:

  • ­Full-field evaluation of settling & decay events
  • ­Non-stationary processes (e.g. fluid machines, valves)
  • ­Environmental tests with variable excitation profiles or temperatures
  • ­Run-up of electric drives and combustion engines
  • ­Transient events (e.g. shock, switching)

The Polytec MPV software allows you to conveniently configure all the channels (including the reference channels) and the optional signal generator. The deflection shapes in both the time and the frequency range are shown superimposed on the object geometry in 3D for analysis purposes.

You can use the MPV-800 Multipoint Vibrometer to conduct measurements on lightweight or hot objects – especially those with sensitive or soft surfaces – without influencing the sample. Such measurements also include biomedical applications, where the eye-safe laser technology is particularly beneficial.
