Faster results with QTec® multi-path interferometry
The patented QTec® multi-path interferometer technology boosts the signal quality of infrared laser vibrometer (SWIR) decisively. It 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.
