全场扫描式激光测振仪

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.
