摘要
开环全保偏光纤陀螺结构简单，有使用价值，进入９０年代国外研究成功熔接型保偏光纤耦合器以后，这种陀螺更受重视，向实用方向发展．对研究全保偏光纤陀螺中的几个关键问题：光路中元器件的特性；保偏光纤的对轴熔接技术；零漂和噪声做了分析．实验结果表明，陀螺的零漂（１σ）达到了１．２４°／ｈ．
Open-loop all PM-fibre gyro with simple configuration has high use value.Since thefused-type PM optic fibre coupler was produced successfully in the early 90's.this kind ofgyro with such configuration was paid much attention to and was developed towaxd practicaltype. This article analyses some key points, for example. performance of components in theoptic circuit. technique of finding axes and fusing of PM--fibre, drift and noise for the openloop all PM-fibre gyro. The result of experiment shows that the drift of gyro keeps below1. 24°/h.
