摘　　要：无衍射光束近年来广受关注,其无衍射、自修复和自加速的传播特性在微观成像应用中显示出潜在的优势。无衍射特性可抑制光束在传播过程中的衍射,有助于提升成像的分辨率。自修复特性可使光束在透过强散射介质后快速恢复波前,提高成像景深和信噪比。自加速特性可增加光场信息的有效探测维度,实现多维重构成像。本综述结合几类生物显微成像技术特点,介绍以贝塞尔光束、艾里光束为代表的无衍射光束在高分辨生物显微成像中的应用研究进展。Non-diffracting beams have attracted attention in recent years due to their unique properties,such as diffractionfree propagation and self-repairing and self-accelerating ability,which make them promising candidates for microscopic imaging applications.Non-diffraction beams can suppress beam diffraction during propagation,thereby improving the imaging resolution.Moreover,their self-healing characteristic facilitates quick wave-front recovery after passing through a strongly scattering medium,enhancing imaging depth and signal-to-noise ratio.Their self-acceleration feature expands the detection dimension of light field information,enabling multi-dimensional reconstruction imaging.Based on the characteristics of several biological micro-imaging technologies,this paper discusses the application and research progress of non-diffracting beams,specifically Bessel and Airy beams,in high-resolution biological micro-imaging.
