    中文摘要:
          液位测量传感器是飞机燃油测量系统中的重要组成部分。光纤燃油液位传感器因其本质安全的特性而在飞机燃油液位测量领域备受关注。根据被测对象对光的调制形式不同，将光纤液位传感器分为光强调制型和波长调制型两类，总结各种传感器的原理和应用现状，讨论不同类型传感器的性能和优缺点，并对今后的发展方向做出展望。
    英文摘要:
          Fuel level measurement has always been an import issue in aircraft fuel system. Optical fiber fuel level sensors have attracted more and more attentions in aircraft fuel level measuring field because of its intrinsic safety. This paper classifies all the optical fiber fuel level sensors into two types according to the way to modulate the optical parameters: light intensity modulation and wavelength modulation. Not only is the principle of the sensors introduced, but also the current development status is presented. Finally, the application tendency is discussed.
