Supermedia User Interface for Scanning Probe Microscopy

当利用扫描隧道显微镜(SPM)作为一种纳米操作工具时,由于其缺乏实时的传感器信息反馈,而大大阻碍了它的广泛应用.利用超媒体人机交互接口可以解决这个问题.在纳米操作过程中,超媒体接口不但可以为操作者提供可实时更新的仿真操作场景,还可以通过力反馈手柄让操作者实时地感受到探针受到的三维纳米操作力.除此之外,操作者还可以通过该手柄直接控制探针的三维运动.最后在聚碳酸酯上进行了超媒体人机接口的纳米刻画实验.实验结果验证了该系统的有效性和效率.

When Scanning Probe Microscopy(SPM) is used as a nanomanipulation tool, its lack of real-time sensory feedback has hindered its wide application. In this paper, a supermedia user interface is developed to overcome this problem. The supermedia interface can not only provide the operator with real-time visual feedback of the scanned image, but also let the operator feel 3D real-time nanomanipulation force. Furthermore, the operator can directly control the 3D motion of SPM tip through a joystick. Some experiments are done with the application of supermedia interface in nano-umprint on polycarbonate.The results demonstrate the efficiency and effectiveness of the supermedia user interface.
