Laser Doppler vibrometers
Laser Doppler vibrometers from Polytec are precision vibration sensors and comprehensive optical testing solutions representing the globally established gold standard for non-contact vibration analysis. The sensor and measurement instruments portfolio offers solutions to any vibration, acoustics and dynamics 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 studying full-field structural vibrations: Polytec laser vibration sensors provide a fast and precise, non-contact and therefore non-intrusive measurement solution.
Do you have any questions about our laser Doppler vibrometers?
Single-point vibrometers
Single-point laser Doppler vibrometers measure transfer functions, amplitudes and resonance frequencies without contact in a non-intrusive way thanks to the simple “point and shoot” principle. Single-point vibrometers are laser vibration sensors that measure object vibrations in the direction of the laser beam (out-of-plane motions). From modular concepts to robust industrial vibrometers or compact designs – Polytec will always provide you with the ideal measuerement tool to solve your individual vibration measurement task.
Full-field vibrometers
Full-field vibrometer are vibration measurement systems that allow engineers to conduct areal deflection shape measurements as fundament for validating simulation models and identifying vibration hotspots. They keep the focus firmly on complex vibration behaviour over the entire surface. Polytec’s product range includes everything from scanning vibrometers for stationary processes to multipoint vibrometers (that measure in parallel) for non-stationary and transient processes.
Microscope-based vibrometers
Inspired by the rapid further development of microelectromechanical systems and MEMS, Polytec presents this highly innovative product line of microscope-based measurement systems. MSA Micr System Analyzers from Polytec validate dynamics and topography of microsystems reliably with utmost precision.
Special-application vibrometers
Special testing needs may require special measurement tools. Whether measuring ultrasonic applications in the very high frequency range, or rotational vibrations on rotating structures, or in-plane vibrations measuring vibrations perpendicular to the measurement beam – there is a Polytec special vibrometer to provide the perfect solution.
Software
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.
Accessories
Every application has its own measurement challenge. Here, the application-oriented setup and accessories make the difference, making metrology become a complete solution. For Polytec designers and engineers, comfort and flexibility are values with high priority, to make your Polytec vibromters work in any situation you need.
