Abstract
A sensing arrangement () is described. The arrangement comprises: a moveable object () including a plurality of marker portions () disposed in a calibrated configuration, each marker portion () being capable of emitting light in response to stimulation. The arrangement also includes a light source () directed towards the marker portions () and for causing light emission therefrom. An imaging device () is directed towards the marker portions () and includes an array of light-detecting elements for sensing light emitted from the marker portions () to generate image data. A processor (), in communication with the imaging device (), analyses image data received from the imaging device () to determine the location of the moveable object () based on the calibrated configuration.
