Laser Doppler vibrometers
Polytec vibration sensors are laser Doppler vibrometers that have become the globally established gold standard for non-contact vibration analysis. The complete product portfolio offers solutions to any vibration measurement task in research, development, production testing and long-term monitoring. Whether single-point or differential measurement, determining rotational vibrations or in-plane motions, visualizing the dynamic behavior of microsystems or full-field structural vibrations: Polytec laser sensors provide a quick, non-contact and non-intrusive measurement solution.
Single-point vibrometers
Measuring the transfer functions, amplitudes and resonance frequencies in a non-intrusive way with the simple “point and shoot” method is the single-point vibrometer’s specialty. You measure an object’s vibrations in the direction of the laser beam. From robust industrial vibrometers, to particularly compact designs, or systems with a modular approach – Polytec will always provide you with the ideal tools to suit your individual vibration measurement task.
Full-field vibrometers
Full-field vibrometers keep the focus firmly on complex vibration behaviour over the entire surface and work contactlessly according to the laser Doppler principle. Polytec offers you turnkey solutions for everything from characterizing stationary vibration processes with scanning vibrometers to multipoint vibrometers (that measure in parallel) for non-stationary and transient processes. They shorten development times by giving you a comprehensive and precise insight into the dynamic behaviour of vibrating structures. They visualize eigenmodes and operational deflection shapes in a meaningful way and provide you with data quality that takes simulation model validation to a whole new level. Full-field vibrometers are complete solutions that are made up of sensor technology, data acquisition and analysis software. You can gradually retrofit and expand all the systems and also fully automate scanning vibrometers as your requirements grow.
Innovative measurement solutions for characterizing MEMS
Inspired by the rapid further development of microelectromechanical systems and MEMS, Polytec presents this highly innovative product line of microscope-based measurement systems for reliable validation of microsystems’ dynamics and topography. Determine transfer functions, and use unique all-in-one instruments for both the static and dynamic 3D characterization of microsystems, measure through Si encapsulations, and integrate your test-setup into (vacuum) probe stations.
Special-application vibrometers
If you’ve got special requirements, then you need special tools. No matter whether you’re carrying out measurement for ultrasonic applications in the very high frequency range, or need rotational vibrometers for rotating structures, or in-plane vibrometers for measuring vibrations perpendicular to the measurement beam – you’ll find the perfect solution at Polytec.
Powerful software for vibrometry
Data acquisition, visualization and evaluation form the very essence of Polytec’s high-tech vibration measurement tools. And for this very purpose, Polytec is offering you high-performance software packages for device control, data acquisition and data processing that enable users to represent their measuring results in an intuitive and animated way and to exchange data with external software for the purpose of experimental modal analysis or FEM calculation, for example.
