摘要
随着材料和技术的不断发展,偏振式光纤电流传感器的性能和精度相比过去有了很大的提升,已经能够初步满足当今的工程实际需求。回顾偏振式光纤电流传感器的发展,关键的技术逐步被突破,如温度补偿、线性双折射的抑制、变旋转率光纤、集成光波导技术以及旋转高双折射光纤的制作。基于这些新技术,一种新的偏振式电流传感器被提出。该传感器采用单模光纤进行引导,具有结构简单、精度高、成本低的优点。
With the continuous development of materials and technologies, the performance and accuracy of plarimetric current sensors have been greatly improved compared to the past. They have been able to meet the actual needs of today’s projects. Looking back at the development of polarized fiber current sensors,the key technologies are gradually breakthroughs,such as temperature compensation,suppression of linear birefringence,variable rotation rate fibers,integrated optical waveguide technology,and the production of spun highly birefringence fibers. Based on these new technologies,a new polarimetric current sensor is proposed. The sensor is guided by the single mode fiber. It has a simple structure,high accuracy,and low cost.
