Polytec 3D Scanning Vibrometers (PSV-3D) complete your vibration measurement tasks in research and product development in a reliable and precise way. The deflection shapes and Eigen modes detected help you with everything from NVH, acoustic and structurally dynamic issues to ultrasonic analyses, FEM validation and non-destructive testing.
The PSV-3D 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.
- Non-contact laser vibration measurement
- Full-field measurement with high spatial resolution
- Open data and control interfaces for simple adaptation to your application
- Can be extended to create a fully automatic RoboVib® Structural Test Station
- Versatile accessories and software options
Model validation based on operational deflection shapes
Since in-plane data and out-of-plane data are measured simultaneously, the PSV-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 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, also check out the new PSV QTec Scanning Vibrometer.
If your requirements increase, you can easily retrofit the 3D Scanning Vibrometer or expand it to include a fully automatic RoboVib® measuring station.
