| 摘 要： | 敏感线圈的热非互易性是引起光纤陀螺温度漂移的重要因素之一，因而人们多采用四极对称技术（ＱＡＤ）绕制光纤线圈。本文结合光纤陀螺研制中的实际状态，对Ｍｏｈｒ温度模型进行了修正和推广，研究了非理想ＱＡＤ环圈结构的温度漂移特性。这对于光纤陀螺及其环圈的优化设计具有指导意义。

| Abstract: | The thermal nonreciprocity in sensing coil is one of sources induced temperature drift in FOG ,so the fiber loop is usually wound by quadrupole(QAD) symmetrical technique.In this paper,Mohr's temperature model is modified and extended to imperfect QAD coils,and the behaviour of temperature drift for imperfect QAD coils is studied by simulation.The important conclusion is helpful to engineering design of FOG and its coil. |
