摘 要: 由于缺乏实时的传感器信息反馈,导致传统的基于原子力显微镜的纳米操作盲目,操作效率和成功率都非常低。为了克服这一问题,设计和实现了一种具有实时视觉和三维触觉反馈的纳米操作系统。当利用该系统进行纳米操作时,操作者不但可以实时感受到探针与被操作物体间的相互作用力,还可以在3D增强现实图像界面中观察到纳米操作场景的变化,并可以在线控制探针的三维运动。这种交互式的操作系统使得纳米操作变得容易可行。纳米刻画实验和多壁碳纳米管的推动宾验验证了该系统的有效性和高效率。 An AFM based nanomanipulation system with real-time visual and force feedback is developed aiming to overcome the problem of low manipulation efficiency and effectiveness in the traditional AFM based nanomanipulation bacause of its lack of real-time sensory feedback. During nanomanipulation, the system can not only provide the operator with real-time visual feedback which displays the real-time nano-environment and a real-time dynamic tip position, but also let the operator feel the 3-D real-time operation force. Furthermore, the operator can directly control the tip 3-D motion of AFM through a joystick, which makes AFM based nanomanipulation feasible and applicable. The nano-lithography and MWCNTs pushing experiments demonstrate the efficiency and effectiveness of the system.
