Because mz interferometric optical fiber gyroscope has bigger nonreciprocal phase, the system thermal stability, polarization noise and the error caused by the fluctuation of light source is particular analysed, some effective methods is proposed such as : using the " quasi - white - light " interferometry and the fiber polish technology accurately to control the fiber length, using depolarization light to minish the polarization error, and using temperature control, optical power control and depolarizer to stabilize the output of the light source
結合mz干涉式光纖陀螺的存在較大非互易相移的特點,著重從其溫度穩定性、偏振噪聲以及光源波動引起的誤差三個方面分析了抑制噪聲、提高檢測精度的方法,提出了:採用「準白光」干涉測量法結合光纖研磨技術精確控制光纖長度差的辦法;採用非偏振光源抑制偏振噪聲的方法;採用溫度控制、功率控制以及消偏器實現穩定化陀螺光源的方法。Compared with d - shaped fiber, the d - shaped fiber bragg grating index sensor is more precise and reliable because the sensed information is encoded into wavelength, which is an absolute parameter, the output does not depend on the light levels, loss in the connecting fibers and couplers, or source power
光纖布喇格光柵傳感器以波長偏移和功率變化同時作為傳感度量,由於波長檢測對光功率漲落不敏感,相對于只以功率變化作為傳感度量的傳感器件,具有更高的傳感精度和準確性。4. a 8 - cascaded wavelength - division - multiplexed fiber bragg grating sensor system was interrogated by changing voltage acting on a employed tunable fabry - perot filter, and a feedback loop was introduced to make filter track the shifted wavelength of the sensor. at the same time an unbalanced scanning michelson interferometer was introduced to demodulate sensor signal
同時為克服查詢某一光柵時,應變引起波長漂移導致反射波長偏離f - p透過波長,利用一反饋控制裝置,使得濾波器的透過波長自動追蹤查詢光柵的布一拉格波長,利用非平衡掃描michelson干涉儀對傳感信號進行了高解析度的解調。
