| Popis: | Methods for imaging vibrations in mechanical resonators have been limited to picometer amplitudes and frequencies above 2 GHz. Here, the authors use a stroboscopic optical sampling approach, with simultaneous high bandwidth and low noise-floor, and measure 70 fm displacements out to 12 GHz. |
