In recent years there has been an increasing need of ultra precision positioning and scanning systems with nanometer, or even subnanometer, resolution and accuracy. To meet the demand requires the development of new design concepts and techniques. A

Capacitance micrometry is a technique for measuring the relative displacement of two surfaces. As the spacing between the two surfaces changes so the capacitance changes. This short paper is a summary of recent measurements made to characterize and u

Using TAURUS – an Imaging Fabry Perot system in conjunction with the IPCS on the AAT, we have studied the velocity field of the Ha emission line at a spatial resolution of 1.7″ over the dark lane structure of Centaurus A. The derived velocity fie
