Beschreibung
Zusammenfassung:	An optical microphone comprises a light source configured to emit a light beam and an acoustic sensor configured to reflect the light beam. The acoustic sensor includes single-wall nanotubes and deflects in response to pressure waves. An optional reflector of the optical microphone is configured to re-reflect the light beam from the acoustic sensor. A detector is configured to detect the light beam from the acoustic sensor or the reflector, and thus measures the pressure waves.
