    • A fiber optic enclosure assembly for protecting an optical fiber includes a tubular body member, an end member and a coupling member. The tubular body member has first and second opposed ends and defines an interior body passage to receive a portion of the optical fiber. The end member is separately formed from the body member and is mounted on the first end thereof. The coupling member is directly bonded to each of the body member and the end member to secure the end member to the body member and to form an environmental seal between the end member and the body member. The body member and the end member are formed of dissimilar materials, the material of the body member being more flexible than the material of the end member. The coupling member is formed of a material capable of forming a secure bond with both the material of the body member and the material of the end member.
    • 用于保护光纤的光纤外壳组件包括管状本体构件,端部构件和联接构件。 管状本体构件具有第一和第二相对端并且限定用于容纳光纤的一部分的内部主体通道。 端部构件与本体构件分开形成并安装在其第一端上。 联接构件直接接合到主体构件和端构件中的每一个上,以将端构件固定到主体构件并且在端构件和主体构件之间形成环境密封。 主体构件和端构件由不同的材料形成,主体构件的材料比端构件的材料更加柔性。 联接构件由能够与本体构件的材料和端构件的材料形成牢固结合的材料形成。

    • A system is disclosed which suppresses relative intensity noise in a fiber optic gyroscope. A high-speed intensity modulator is placed in the gyroscope light path between the fiber light source and a tap coupler which provides a sample of the modulated signal for use in a feedback loop. A photodetector receives the sampled signal and provides current-to-voltage conversion of the signal. A high-bandwidth voltage amplifier then adjusts the gain and phase of the converted signal and drives the intensity modulator in such a manner as to stabilize the control loop and provide suppression of relative intensity noise. The present system modulates the intensity of the light at a frequency which is sufficiently high to allow suppression of high frequency components of the relative intensity noise.
    • 公开了抑制光纤陀螺仪中的相对强度噪声的系统。 将高速强度调制器放置在光纤光源和抽头耦合器之间的陀螺仪光路中,该抽头耦合器提供用于反馈回路中的调制信号的采样。 光电检测器接收采样信号并提供信号的电流 - 电压转换。 然后,高带宽电压放大器调整转换信号的增益和相位,并以稳定控制回路并提供相对强度噪声的抑制的方式驱动强度调制器。 本系统以足够高的频率调制光的强度,以便抑制相对强度噪声的高频分量。
