摘　　要：结构光束是指在空间和时间上“定制”的光场,其振幅、相位和偏振态在空间和时间上有着特殊的分布。近些年,结构光束的研究发展迅速,光学参量的特殊分布从特定的空间横向结构、纵向结构,发展到定制的时空结构。这种具有不同时空结构的光束为众多领域带来了突破,包括光学通信、光学传感、光学微操作、量子信息处理和超分辨率成像。因此,人们提出了许多方法,并制造了相关器件,通过调整光束的各种光学参量在空间域和时空域的分布来生成结构化光束。本文主要介绍不同类型结构光束(包括空间结构光束以及时空结构光束)的制备方法,对已产生的结构光束进行了总结,并进一步讨论和展望了结构光束在未来的发展方向。A structural beam refers to a light field that is“customized”in both space and time,characterized by its unique distribution of amplitude,phase,and polarization state in both space and time.Recently,research on structured light beams has developed rapidly.This has led to the evolution of a special distribution of optical parameters from specific spatial transverse and longitudinal structures to customized spatiotemporal structures.This type of beam with different spatiotemporal structures has brought breakthroughs in many fields,including optical communication,optical sensing,optical micromanipulation,quantum information processing,and super-resolution imaging.Therefore,various methods have been proposed,and related devices have been manufactured to generate structured light beams by adjusting the distribution of various optical parameters of the beam in spatial and spatiotemporal domains.This study mainly introduces the preparation methods for different types of structured light beams,such as spatially structured and spatiotemporal structured beams.Therefore,it provides a comprehensive overview of the generated structured beams,along with a discussion and outlook on the future development direction of structured beams.
