查询词典 vibrometer

Out-of-plane displacement and tolerance can be measured by integrating Mirau microscopic interferometry with stroboscopic photography, and the repeatable accuracy of out-of-plane displacement is 3 nm. Laser Doppler vibrator has an advantage of analyzing the motion in frequency domain, and it is the complementarity of measuring periodic motion in time domain.
