Abstract

This work describes an automated opto-fluidic system for parallel non-contact manipulation of microcomponents. The strong dynamics of laser-driven thermocapillary flows were used to drag microcomponents at high speeds. High-speed flows allowed to manipulate micro-objects in a parallel manner only using a single laser and a mirror scanner. An automated process was implemented using visual servoing with a high-speed camera in order to achieve accurately parallel manipulation. Automated manipulation of two glass beads of 30 up to 300 μm in diameter moving in parallel at speeds in the range of mm/s was demonstrated.

摘要

这项工作描述了一种用于微组件并行非接触式操作的自动化光流体系统。利用激光驱动热毛细流的强大动力学特性以高速拖动微组件。高速流动使得仅使用单个激光器和一个镜面扫描仪就能以并行方式操纵微物体。通过使用高速摄像机进行视觉伺服实现了自动化过程，以实现精确的并行操纵。展示了对两颗直径为30至300μm的玻璃珠进行自动化操纵，它们以毫米/秒范围内的速度并行移动。
