摘要:

光学捕获描述了光与物质之间的相互作用,通过动量转移来操纵微观物体。在用单个光束进行3D捕获的情况下,这被称为光镊。光镊是一种用于操纵小物体的强大且非侵入性的工具,在许多领域,包括物理学,生物学,软凝聚态物质等,都变得不可或缺。在早期,光学捕获通常与单个高斯光束一起使用。近年来,我们目睹了在光学捕获中使用具有定制相位、振幅和偏振的结构光束的快速进展。光束的轴上相位奇异性、传输不变性等特性为液体、空气和真空中的微操作研究提供了新的可能性。本文综述了近年来利用结构光进行光阱研究的进展。

英文摘要:

Optical trapping describes the interaction between light and matter to manipulate micro-objects through momentum transfer. In the case of 3D trapping with a single beam, this is termed optical tweezers. Optical tweezers are a powerful and non-invasive tool for manipulating small objects, which have become indispensable in many fields, including physics, biology, soft condensed matter, amongst others. In the early days, optical trapping were typically used with a single Gaussian beam. In recent years, we have witnessed the rapid progress in the use of structured light beams with customized phase, amplitude and polarization in optical trapping. Unusual beam properties, such as phase singularities on-axis, propagation invariant nature, have opened up novel capabilities to the study of micromanipulation in liquid, air and vacuum. In this review, we summarize the recent advances in the field of optical trapping using structured light beams.
