水下传感器具备非凡的“听觉”
日前，一个国外的研究小组开发了一个水下声学传感器，它能地判定声源的方向，从而改进那些早期的水听器。该传感器的灵感来源于鱼的内耳解剖结构，它用绒毛的运动对声波作出响应，因此传感器采用铰链连接的两个平板。一个平板固定在某个位置，另一个是采用与水密度相匹配复合材料制造的可自由运动平板。第二个平板的运动改变一根光纤中的信号，研究人员用一只光电二极管对其作分析。
该项目由*管理部门出资，进行资金支持，它可以帮助*减少拖拽在船边的传感器阵列长度，可地测定水下物体的位置，包括潜艇，也就是说水下传感器也可再军事上有所应用，功能十分强劲。
我公司主要经营变频器，纠偏，触摸屏，PLC，伺服，限位开关，传感器，编码器等
