Recent advances in dynamic holography have resulted in spatial light modulators capable of producing an almost limitless variety of field distributions from a single incident beam. Holographic assembly is a technique that exploits this capability to generate and control multiple foci that can be used to trap and manipulate nanoparticles. Although the forces associated with conventional optical tweezers are well understood, the effects arising from the more complicated interactions associated with holographic assembly are not. We present a general and flexible method, based on T matrix theory, for investigating these effects and use it to calculate the forces between particles in a variety of optical environments.
动态全息术的最新进展已带来了空间光调制器，这种调制器能够从单个入射光束产生几乎无限多种场分布。全息组件是一种利用这一能力来生成和控制多个焦点的技术，这些焦点可用于捕获和操纵纳米粒子。尽管与传统光镊相关的力已得到充分理解，但与全息组件相关的更复杂相互作用所产生的影响却并非如此。我们提出了一种基于T矩阵理论的通用且灵活的方法来研究这些影响，并利用它来计算各种光学环境中粒子之间的力。
