光纤偏振器具有抗干扰能力强，插入损耗小，易与光纤系统连接等优点，在光纤相干通信系统．以及光纤相干传感系统中受到重视。文中系统地讨论了电磁挤压型、可旋转光纤线圈型、可旋转光纤曲柄型、法拉第旋转器型、线性双折射光纤型，以及改进型和保偏光纤伸展型等光纤偏振器的工作原理和结构，分析了它们的特点，为新型光纤偏振控制器的设计提供了参考。
Optical fiber polarizer with anti-interference ability, low insertion loss, easy connection with the optical fiber system, etc., in optical fiber communication systems. As well as optical fiber coherent sensing system. This paper systematically discusses the working principle of the electromagnetic squeeze type, rotatable fiber coil type, rotatable fiber crank type, Faraday rotator type, linear birefringence fiber type, and improved and polarization maintaining optical fiber polarizers Structure, analyzed their characteristic, has offered the reference for the design of the new type optical fiber polarization controller.
