Nanopositioning for storage applications
In nanotechnology applications, nanopositioning, i.e., nanometer-scale precision control at dimensions of less than 100 nm, plays a central role. One can view nanopositioners as precision mechatronics systems aiming at moving objects over a certain distance with a resolution that could be as low as a fraction of an Ångström. Actuation, position sensing and feedback control are the key component...
متن کاملCalibration of Nanopositioning Stages
Accuracy is one of the most important criteria for the performance evaluation of microand nanorobots or systems. Nanopositioning stages are used to achieve the high positioning resolution and accuracy for a wide and growing scope of applications. However, their positioning accuracy and repeatability are not well known and difficult to guarantee, which induces many drawbacks for many application...
متن کاملHigh-speed spiral nanopositioning
Nanometer-precise positioning at ultra-high velocities is a major challenge for rapidly emerging applications that use scanning probes in order to observe and alter the properties of materials down to the nanoscale. Typical examples include surface imaging, nanolithography and data storage. For example in probe-based data storage, constant linear velocity along the scan trajectory is required, ...
متن کاملSignal transformation approach to fast nanopositioning.
High bandwidth, high resolution positioning is a significant enabling tool for nanotechnology. Unfortunately, in a typical nanopositioner operating in closed loop, higher bandwidth results in increased sensitivity to measurement noise and hence reduced resolution. In this article we present a technique that allows high-precision tracking of repetitive, jitter-free reference signals without bein...
متن کاملTime Domain Resolution of Nanopositioning Systems
In this article, the resolution of a nanopositioning system is defined as the smallest distance between two non-overlapping points. Techniques are then described for estimating the closed-loop resolution from time-domain recordings of the contributing noise sources. Practical guidelines are also discussed to ensure statistically valid estimates. Experimental results show that the resolution of ...
