Sagnac效应在光纤水听器中的应用
Application of the Sagnac effect in the optical fiber hydrophone
  
中文摘要:
      本文介绍了由Sagnac效应组成的光纤水听器原理,着重推导了声压作用下的光纤水听器的相位变化关系.并在此基础上对比了Sagnac光纤水听器与Mach-Zehnder光纤水听器,结果表明Sagnac光纤水听器在低频段的灵敏度及其实现的简易性上具有很大优势.
英文摘要:
      In this paper, the principle of optical fiber hydrophone based on the Sagnac ef fect is introduced, and its phaes changw dnder the action of the acoustic wave is emphati cally deduced. Comparing the Sagnac hydrophone with the Mach-Zehnder hydrophone, it is shown that the measure sensitivity of the Sagnac hydrophone in the low-frequency range and its use in practice have great advantages over the latter.
