光频域偏振测量(OFDP)是一种基于扫频激光干涉原理的分布式光纤偏振测试技术,它能够精确获取保偏光纤、器件、组件与光路的偏振特性及其空间分布,实现高性能器件与光路的性能测试与质量评价,以及缺陷分析与故障诊断。OFDP优点是可兼顾超高测量灵敏度、超大测量范围、高精细度、长测量距离、动态快速测量等,已逐渐发展成为性能最优的分布式光纤测量技术之一。本文回顾了OFDP的测量原理,定量分析了分布式偏振串音的测量极限,综述了分布式偏振测试性能提升的若干关键技术,给出了高精度偏振器件与光路的测试典型应用,并讨论了其技术挑战和未来潜在的研究方向。
Optical Frequency Domain Distributed Polarization Measurement Technology and Applications(Invited)
Optical frequency domain polarimetry(OFDP)is a distributed fiber polarization measurement technique based on optical frequency domain interferometry principles.It accurately measures the spatial distribution of polarization crosstalk and polarization extinction ratio for polarization maintaining fibers,components and devices,and optical fiber system,thereby achieving performance tests,quality evaluation,defect analysis,and fault diagnosis for high-performance polarization maintaining components.Its advantages include ultra-high polarization crosstalk measurement sensitivity,ultra-large dynamic range,high spatial resolution,long measurement distance,and agile measurement.Thus,it becomes one of the distributed fiber measurement technologies with the best overall performances.This paper reviews the measurement principle of OFDP technology,quantitatively analyzes the measurement accuracy limit of distributed polarization crosstalk.Then,the performance improvement technologies for distributed polarization measurement are summarized.Finally,OFDP's applications for measuring typical high-precision polarization maintaining devices are demonstrated,and the technology challenges and future development directions are discussed.
