Full-Field Laser Vibrometers

Reinventing full-field optical vibration mapping

Polytec 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, featuring frequency ranges up to 25 MHz.
PSV QTec Scanning Vibrometers are available as a compact and portable laptop version or as a practical rack-type workstation, as 1D or 3D system.

Full-field optical vibration measurement

With the PSV-500 Scanning Vibrometer, you reliably and precisely measure vibrations in research and product development. 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 (NDT).

Reinventing 3D optical vibration mapping

Polytec 3D Scanning Vibrometers are state-of-the art for noise and vibration measurement in research and development. Using three 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. PSV QTec 3D Scanning Vibrometers are available as a compact laptop version or as a practical rack-type workstation.

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.

Experimental modal analysis simplified

RotoVib enables automated and full-body experimental modal analysis using Polytec’s optical 3D scanning laser vibrometers. Its easy to set-up hardware and software integrates seamlessly into the Polytec scanning vibration measurement workflow and saves time by automatically repositioning the devices-under-test (DUT) instead of a manual and tedious relocation of the sensor setup. 360° measurements of the DUT are as easy as a measurement from just one side.

Automated experimental modal analysis

The RoboVib® Structural Test Station combines a 3D Scanning Vibrometer with an industrial robot – to create a productive vibration analysis solution. The automated measuring station automatically tests everything from complex components to entire vehicle bodies. Both the amount of time required and the sources of error in experimental modal analysis are reduced significantly. So you can therefore thoroughly test a vehicle body, for example, in just one to two days, whereas you would previously have needed weeks to even prepare for the test itself.
