Signal transformation approach to fast nanopositioning
Review of Scientific Instruments
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 being constrained by the reduction in measurement noise induced positioning resolution.
