Abstract: The current trend for nanopositioning with increased speed has led to the development by Queensgate of a dual sensor system for servo control of single axis displacement stages. The stage and control system is currently being evaluated using optical interferometry developed at the National Physical Laboratory. Preliminary results show the performance of the optical interferometer […]
In most fields of engineering, working to micrometre accuracy is considered to be the standard, with typical high-quality bearings having tolerances within hundreds or even tens of microns. But pioneers working in nanopositioning are now operating at tens of picometres – a million times smaller. For comparison, an atom is around one to five-hundred picometres […]
