ABSTRACT:
A method and system for determining the position of a radiation scattering/reflecting element, where the radiation emitter is provided at a surface of a radiation transmissive element an on which radiation is incident. This incident radiation is scattered/diffused/reflected by the scattering/reflecting element and guided by the transmissive element toward a detector able to determine the position of the element.
