Polytec, with over 400 employees worldwide, helps automotive engineers solve vibration challenges, validate designs and improve component quality through non-contact optical measurement.

Non-contact Laser Doppler Vibrometry (LDV) helps engineering teams:

• Investigate noise and vibration issues through NVH testing on brakes, tyres, electric motors, powertrain housings and other automotive components.
• Understand structural behaviour by visualising vibration patterns and identifying resonances through full-field measurements and modal analysis.
• Validate simulation results by comparing measured mode shapes with finite element models to guide design improvements.
• Reduce measurement setup effort by measuring without attaching sensors or adding mass that could affect small or lightweight structures.

Non-contact 3D Optical Surface Profilers support:

• Surface characterisation: Measure roughness, flatness, step height and surface form.
• Inspection across different scales: Evaluate fine microstructures and larger precision components.
• Manufacturing quality control: Assess surface quality and dimensional deviations to support process optimisation.
