【Abstract】 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.更多还原
