Subtype发明
Abstract本发明公开了一种光纤激光传声扬声系统,包括:光纤激光传声器,用于感受声波,并将声波信号转变为用来表示输出激光波长变化的光信号;泵浦源,用于为光纤激光传声器提供泵浦激光;解调仪,用于将光纤激光传声器输出的光信号转变为电声信号;扬声器,用于将光纤激光传声器采集的声音信号播放出来;波分模块,用于分开泵浦源的泵浦激光及光纤激光传声器的输出激光;连接于光纤激光传声器、波分模块、解调仪、泵浦源之间的光纤,用于传输光信号;电缆,用于解调仪和扬声器之间的电信号传输。利用本发明极大的降低了系统噪音,提高了探测微弱信号的能力,并且避免了传输光纤扰动的影响,提高了系统的稳定性。
