摘要
因为空间变化的偏振分布及独特的高数值孔径聚焦特性,矢量光束在显微成像、表面等离子体、粒子操控等领域都体现出了巨大的应用价值。将矢量光束应用于传统的一些显微成像系统中,将极大提升系统的成像性能,提高显微分辨率,甚至实现超分辨显微成像。综述了矢量光束在几种典型显微成像技术中的应用现状,包括共焦显微成像、受激发射损耗显微成像、全内反射荧光显微成像等,介绍了技术发展的历程,以及实现高分辨率的基本原理、典型结构和实验结果。最后,展望了矢量光束显微成像技术的发展前景。
Due to spatially variant polarization distributions and unique high-numerical-aperture focusing proper- ties, vector beams have shown great application values in some fields such as microscopic imaging, plasrnonics and particles manipulation. When such beams are used in some traditional instruments, their imaging performances will be improved greatly, and the imaging resolution is increased, even achieve super-resolution imcroscopic imaging. The applications of vector beams in some typical microscopy technology including confocal microscopy （CF） , stimulated e- mission depletion microscopy （STED） and total internal reflection microscopy （TIRF） are summarized. Their develop- ment histories are introduced, and the basic principles, system structure and experimental results are described in de- tails. The future development trend is also discussed finally.
