提出并论证了一种基于两段Lyot-Sagnac光纤干涉仪的光纤模式双折射测量技术。我们对几种低双折射光纤进行了精确的测量，结果与已发表的数据一致。在所使用的光谱分析仪的分辨率范围内，这种测量方法在10/sup-3/到10/sup-6/m的双折射长度乘积中是允许的。
We propose and demonstrate a simple and accurate optical fiber modal birefringence measurement technique based on a two-segment Lyot-Sagnac fiber interferometer. We have conducted accurate measurements for several low birefringence fibers and the results are consistent with published data. This measurement method is allowed in the birefringence-length product ranging from 10/sup -3/ to 10/sup -6/ m within the resolution of the optical spectrum analyzer used.
