Calibration of AFM based nanomanipulation system

Using AFM as a nanomanipulation tool has been discussed for more than a decade. However, its lack of real-time visual feedback during manipulation has hindered its wide application. Fortunately, this problem has been overcome by our recently developed augmented reality system. Not only can this new system provide real-time force feedback but real-time visual feedback during nanomanipulation. In order to build this augmented reality system, a lot of parameters are used to model the force interaction, measure the forces, and control the tip motion. In this paper, calibration of all parameters used in the augmented reality system is discussed in details.
