Reinventing full-field optical vibration mapping

Polytec QTec Scanning Vibrometers are state-of-the-art for fast noise and vibration measurements in research and development. They determine operational deflection shapes and Eigenmodes for NVH, acoustics, structural dynamics, ultrasonics, FEM validation and NDT.

PSV QTec Scanning Vibrometers are available as compact and portable laptop version or as a powerful rack-type workstation, as 1D or 3D system. Choose between several models that cover frequency ranges up to 25 MHz or upgrade to a PSV QTec 3D vibration measurement system for comprehensive analysis of both out-of-plane and in-plane motions of vibrating structures.

Highlights

  • Non-contact, full-field vibration measurement with FEM-like spatial resolution
  • Best SNR on engineered surfaces
  • Up to 10x faster on engineered surfaces
  • Professional CAE interfaces for model validation
  • Scanner interface enabling tracking and Continuous Scanning Laser Doppler Vibrometry (CSLDV)
  • Advanced geometry handling for meaningful result presentation

Modal analysis featuring MIMO excitation and 8 input channels

  • Expandable to 3D system

Faster results with QTec® multi-path interferometry

The patented QTec® technology using a heterodyne multi-path interferometer concept provides highest optical sensitivity for high-fidelity measurements on all surfaces, which significantly reduces testing time – even on dark, biological, rotating or moving objects. This safe laser technology is perfect for challenging applications also on distant targets. QTec® makes vibration measurements faster, easier and more reliable than ever – for the most robust, unambiguous results.

Upgrade to PSV QTec 3D

Whenever your demands grow, you may upgrade to a 3D Scanning Vibrometer system. PSV QTec 3D Scanning Vibrometers are state-of-the-art for noise and vibration measurement in research and development. Using 3 independent scanning heads they deliver the full information on all vibrational directions. PSV QTec 3D determines operational deflection shapes and Eigenmodes for NVH, acoustics, structural dynamics, ultrasonics, and FEM validation. The high frequency version up to 25 MHz extends the application range to non-destructive evaluation (NDE) research.

Every PSV QTec integrates perfectly into the CAE world providing interfaces to 3D geometries, modal analysis, and automation. With the right accessories, you can measure even the smallest components, localize and trigger on noise, master even complex geometry and measurement setups and measure in tough test bench conditions or wind tunnels.
