Flexible full-field vibration measurement in 3D

The PSV-500-3D Polytec 3D Scanning Vibrometer completes your vibration measurement tasks in research and product development in a reliable and precise way. The deflection shapes and Eigenmodes detected help you with everything from NVH, acoustic and structurally dynamic issues to ultrasonic analyses, FEM validation and non-destructive testing. The PSV-500-3D Scanning Vibrometer conducts precise full-field measurements of the crosstalk between sensor elements, the propagation of surface waves in non-destructive materials testing or the development of integrated sensor networks for composite materials. It uses the data in both the time and the frequency domain to supply you with easily understandable images and animations. 

Highlights

  • Non-contact and full-field with FEM-like spatial resolution
  • Measures even on tiny structures due to smallest laser spot
  • Measures through water and other transparent media
  • Machine vision tools for easy setup
  • Professional CAE interfaces for model validation
  • Advanced geometry handling for meaningful result presentation
  • Modal analysis featuring MIMO excitation and 8 input channels
  • With open interface, versatile software options and accessories
  • Available as compact laptop version and rack-type workstation
  • Expandable to fully automatic RoboVib® Structural Test Station

Model validation based on operational deflection shapes

Since in-plane data and out-of-plane data are measured simultaneously, the PSV-500-3D allows you to conduct meaningful operational deflection shape analyses and to validate finite element simulation models – for frequencies from DC to 25 MHz and vibrational velocities of 0.01 µm/s to 30 m/s. The precise helium-neon laser (HeNe) with its small laser measuring spot is suitable for measurements on extremely fine structures and even measures in and through water and other transparent media. For challenging measurements on technical surfaces, on dark, biological, moving or rotating test structures, the new PSV QTec Scanning Vibrometer is the ideal choice. 

If your requirements increase, you can easily retrofit the 3D Scanning Vibrometer or expand it to include a fully automatic RoboVib® measuring station.

Automatic 3D alignment

New machine-vision techniques make the non-contact PSV-3D Scanning Vibrometers as easy to use as any handy single-point laser vibration sensor while minimizing training needs. For high fidelity data especially from high frequency tests on medical tools as well as for measuring stress and strain, automatically aligning the 3 superimposed lasers is the key. Here, the machine-vision based feature “3D alignment scan” guarantees µm-precision in X, Y and Z enabling faster test setups and highly reliable measurement results.
