The invention discloses an all-fiber towed linear array, which comprises a light source module, a light sending link, a fiber sensor module, a light returning link and a detector module, the fiber sensor module is composed of a plurality of fiber sensor groups, and each fiber sensor group comprises a fiber hydrophone, a fiber depth sensor and a three-axis fiber gyroscope. The optical fiber depth sensor and the optical fiber gyroscope are used for replacing a piezoelectric type depth sensor and a magnetic heading sensor, the defect that the piezoelectric type depth sensor and the magnetic heading sensor which are installed in an optical fiber towed linear array need to be connected through a cable is overcome, no electronic component and wire are arranged in a wet end array, and the wet end all-optical fiber is achieved; and the wet end reliability of the optical fiber towed linear array is obviously improved.

    本发明公开了一种全光纤拖曳线列阵,包括光源模块,送光链路、光纤传感器模块、回光链路和探测器模块,其中光纤传感器模块由多个光纤传感器组组成,每个光纤传感器组包括一个光纤水听器、一个光纤深度传感器和三轴光纤陀螺。通过使用光纤深度传感器和光纤陀螺代替压电型深度传感器和磁航向传感器,克服了光纤拖曳线列阵内装压电型深度传感器和磁航向传感器需电缆连接的缺点,使得湿端阵内无电子元器件和导线,实现湿端全光纤化,显著提升光纤拖曳线列阵湿端可靠性。
