Abstract: An apparatus may provide a control signal based on an axial position of a controller displaceable along an axis. The apparatus may include a component for displacement with said controller along said axis, a radiation source and detector arrangement configured to direct radiation towards a target region and generate a detector signal dependent upon radiation reflected from within that target region, and a computer processor configured to process said detector signal to determine a measure of distance or change of distance to a reflecting surface region within said target region, and to use said measure to provide said control signal. The component may define a reflecting surface that passes through said target region such that a reflecting surface region is present within said target region with a distance that varies with the axial position of the component along said axis.
