摘　　要：本文对桥式补偿结构在光纤传感器中的应用进行了深入的研究,其补偿效果的优劣主要取决于补偿结构的稳定性.用这种补偿技术的光纤压力传感器系统计量油罐贮量得到优于0.2%的长期稳定性.把这种结构使用在激光雷达光纤传感器系统中同样取得显著的补偿效果.The use of optical bridge compensating technique in fiber opticsensor is studiedthoroughly in this artical. The stability of the compensating structure is essential toachieve good results. A fiber optic pressure sensor based on this compensating structurehas been put into practical operation for oil storage measurement in tanks, and the longterm stability of the sensor is better than 0. 2%, This compensating technique has beenused in a Ladar-fiber optic sensor system and has gained notable results also.
