[9a-N203-2] Dual-comb interferometric vibrometry for absolute vibration amplitude measurement with picometer precision

optical frequency comb,vibrometry,dual-comb interferometry

We have developed a dual-comb-based absolute vibrometry technique that maps surface-vibration profiles with picometer precision. This capability will greatly advance investigations of energy-conversion processes mediated by surface phonons.
