光学诱捕是一种越来越重要的技术，用于控制和探测物质，范围从纳米到毫米。本文介绍了在任意三维配置中创建大量高质量光学陷阱的方法，并在计算机控制下动态重新配置它们。除了形成常规的光镊外，这些方法还可以单独雕刻每个陷阱的波前，从而允许基于不同的光模式的陷阱阵列，包括光涡流，轴向线陷阱，光学瓶，光学瓶和光旋转器。建立大量单独结构的光学陷阱并在三个维度上独立移动它们的能力有望在介观长度范围内进行研究，工程，诊断和制造的新机会。 （c）2002 Elsevier Science B.V.保留所有权利。
Optical trapping is an increasingly important technique for controlling and probing matter at length scales ranging from nanometers to millimeters. This paper describes methods for creating large numbers of high-quality optical traps in arbitrary three-dimensional configurations and for dynamically reconfiguring them under computer control. In addition to forming conventional optical tweezers, these methods also can sculpt the wavefront of each trap individually, allowing for mixed arrays of traps based on different modes of light, including optical vortices, axial line traps, optical bottles and optical rotators. The ability to establish large numbers of individually structured optical traps and to move them independently in three dimensions promises exciting new opportunities for research, engineering, diagnostics, and manufacturing at mesoscopic lengthscales.
