摘　　要：介绍了一种使用偏振分光棱镜的新型光桥式补偿技术，并对因棱镜消光比变化导致的误差进行了研究。基于该补偿结构的光纤压力传感器已实际应用于石化部门油罐储量计量，其现场运行的长期稳定性优于０．２％。A novel optic bridge compensation technique using a polarization splitting prism is introduced,and the errors caused by the changes of prism's extinction ratio are studied.A fiber optic pressure sensor based on this compensating structure has been put into practical operation for oil storage mearurement in tanks,and the long term stability of the sensor is better than 0.2%.
