Nanopositioning for Polarimetric Characterization

Journal of Nanoscience and Nanotechnology, 2008
A positioning system with approximately nanometer resolution has been developed based on a new implementation of a motor-driven screw scheme. In contrast to conventional positioning systems based on piezoelectric elements, this system shows remarkably low levels of drift and vibration, and eliminates the need for position feedback during typical data ...

Impulsive control for fast nanopositioning

Nanotechnology, 2011
In this paper we present a non-linear control scheme for high-speed nanopositioning based on impulsive control. Unlike in the case of a linear feedback controller, the controller states are altered in a discontinuous manner at specific instances in time.
