德国一家名为津海泽尔的公司，开发出了一种可在危险场所通话的光子微音器，并开始批量生产。 这种光子微音器的原理是：一块极薄的振动膜，合着声波的节奏振动；与此同时，一束来自光导纤维的光波，射向该振动膜；振动膜又将这束光波反射给另外的光导纤维，并被传送给光电二极 A German company called Jin Hazel developed a photonic microphone that can talk in dangerous places and started mass production. The principle of this photon microphone is: a very thin diaphragm, the rhythm of vibration along with the sound; at the same time, a light beam from the optical fiber, the vibration of the film; the diaphragm in turn reflects the light beam An additional optical fiber is fed to the photo diode
