Automatic 3D alignment for modal analysis and FE model validation

PSV-3D Scanning Vibrometer simplifiying modal test setups

New image processing techniques make the PSV-3D Scanning Vibrometers from Polytec as easy to use as any handheld laser vibration sensor according to the point-shoot-measure principle, reducing both setup time and training requirements. The 3D Scanning laser Doppler vibration measurement systems have become established tools for all researchers and developers in experimental modal analysis, FE model validation and FEM optimization with respect to NVH (noise, vibration, harshness), acoustics or fatigue testing. Now, the automatic alignment of the three superimposed laser beams is the latest innovation for an even more consistent and reliable collection of measurement data. The new 3D alignment feature shows its potential especially in high-frequency tests, such as on medical devices or for stress and strain measurements. The "3D Alignment Scan" with fast image processing algorithms ensures automatic positioning in all X, Y and Z coordinates with a precision down to the µm range precision. The test setup for modal tests and deflection shape analysis is now even faster and easier with PSV Scanning Vibrometers and always guarantees reliable measurement results right away.
