Basics of vibration measurement
激光多普勒测振法
激光多普勒测振法是目前能够获取最佳位移和速度分辨率的振动测量方法，已被广泛用于基础科学领域。它能实现飞米级的振幅分辨率，线性度高，在极高频率范围内（当前已超过 1GHz）仍能确保振幅的一致性。
Vibrometry typology
Single-point measurement, measuring with multiple laser beams at the same time, areal scanning of entire surfaces or three-dimensional vibration shape analysis. Learn more about the different types of Polytec vibrometers.
