摘　　要：理论分析了非理想工作状态下闭环光纤陀螺的输出与探测光功率的关系.实验研究了探测光功率发生变化时,由电路误差导致的闭环光纤陀螺附加零偏的变化特性,明确指出了两者之间的关系.探讨了光路缺陷导致的附加零偏与光功率的关系,指出在作者实验室目前的技术条件下,观察不到由光路缺陷导致的附加零偏与光功率的关系,但不能肯定光路缺陷导致的附加零偏与光功率一定无关.The relation between the light power and the output of imperfect closed-loop interferometric fiber optic gyroscope（IFOG） was investigated theoretically. By changing the light power,the characteristic of the bias of closed-loop IFOG with imperfect electric system was studied experimentally. The relation between the excess bias caused by electronic system and the light power was provided definitely. The relation between light power and excess bias that came from imperfect light system was discussed, and it was shown that under author＇s present condition, the excess bias had almost no relationship with the detected light power. However,it was still a question whether they had any relationship or not.
