摘　　要：回顾了光场相干与偏振联合调控的研究进展,重点介绍了具有特殊空间相干结构的二维部分相干矢量光束的表征、合成及在复杂环境中的鲁棒传输特性;结合纳米光子学的发展,将二维部分相干矢量光束推广到了三维部分相干矢量光场,给出了三维部分相干矢量光场的相干与偏振表征,分析了部分相干紧聚焦矢量光场中的三维偏振结构,包括偏振维度、三维非寻常偏振态、自旋角动量结构等。研究表明相干性在赋予了矢量结构光场新颖自由度的同时,导致了二维矢量光束的鲁棒传输特性以及紧聚焦矢量光场新型三维偏振结构。Significance Coherence and polarization are two intrinsic properties of optical fields.The investigation of optical coherence has boosted the development of partially coherent optics,while the study of polarization properties has led to the discovery and application of optical structured vector fields.For a long time,the coherence and polarization properties of optical fields were generally treated as independent degrees of freedom and often studied separately.Since the 1990s,researchers have gradually realized the inherent correlation between the coherence and polarization properties of optical fields.It has been recognized that coherence and polarization properties can interact during light beam propagation or in the interaction of light with complex media.The joint control of coherence and polarization has driven the study of partially coherent vector optical fields.However,previous research mainly focuses on electromagnetic Gaussian Schell-model beams,whose coherence structure follows a Gaussian distribution.Recently,with the emerging research on light field manipulation and structured light,and the development of theories and technologies for controlling the coherence structure of optical fields,the research focus on partially coherent vector beams has gradually shifted toward those with special spatial coherence structures.Due to the control of vectorial coherence structures,these beams exhibit characteristics during propagation that are completely different from traditional electromagnetic Gaussian Schell-model beams.They have potential applications in far-field polarization shaping and optical super-resolution imaging.Furthermore,with the rapid development of nano-optics,research on three-dimensional optical fields has emerged.Studies have indicated that due to the modulation of coherence,partially coherent vector fields exhibit rich three-dimensional polarization characteristics.We review the research progress on the joint control of coherence and polarization in optical fields,with a focus on the charac
