Measurement Record

Caption

The optical measurement record (blue trace) shows peaks at all frequencies at which the membrane can resonate, from the fundamental mode, marked (1,1), to many overtones. From this characteristic pattern the researches can tell the location at which the laser beam hits the membrane (inset). Remarkably, already the quantum fluctuations of the laser light excite the membrane modes.
