  1. The theoretical analysis shows that mz - ifog can be used to detect the rotation rate of moving objects. a systematic analysis of transfer characteristics of mz - ifog is made. performance - limiting factors, including the path - length difference, the disturbance of temperature fluctuation and stress from working environment, the quality of light source, are all discussed along with methods to reduce their effect on the output signal

    本文用系統的方法分析了mz型干涉式光纖陀螺儀的光傳輸特徵,指出了其較大的非互易性因素-臂長差的存在,分析了工作環境因素(溫度,應力) 、光源質量(輸出光束中心波長、光功率波動及偏振態波動)對系統工作性能的影響,並指出了減少系統非互易因素、抑制噪聲、提高檢測穩定性的措施。
  2. A distant field interference of non - single - core light beams is analysed in a transparent liquid or solid when the bubble is irradiated with laser, a formula on optical path length difference is derived, interference regions and causes of interference rings thick inside and thin outside are analysed, the diameter of bubble can be measured by method of interference, the size of bubble and refraction index of gas inside the bubble can be measured in the depths of medium

    摘要對透明液體、固體中氣泡在激光照射下產生的一種非單心光束干涉進行了遠場分析,得到了程差公式,分析了干涉的區域、圓環狀干涉條紋內密外疏的原因,通過干涉的方法可以測量氣泡的直徑,能夠用於介質深處氣泡尺寸及泡內氣體折射率的測量。
  3. To compensate for low - frequency drift of the optical path - length difference and to keep the operation point on the most sensitive point, the reference mirror is adjusted with a actuator driven by a feedback loop

    為了補償光程差的低頻漂移,將工作點穩定在靈敏度最高點,使用一個反饋控制系統驅動微位移器調整參考平面鏡。
