| 摘 要： | 本文介绍了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。

| Abstract: | 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. |
