產(chǎn)品名稱：非接觸式激光測(cè)振儀
The AT Series Laser Doppler Vibrometer can measure the vibration of an object without contact, by means of the optical heterodyne method. By FM-demodulating the difference in frequency between reference and measured light, the AT Series can detect the speed and frequency of an object's vibration, rendering microvibration measurement possible.
The wide range of AT Series applications includes pickups for DVDs, CDs, and HDDs, vibration analysis of audio equipment, as well as applications relating to the auto industry, general plant equipment, and micromachines.
