Abstract
There is disclosed a sensing device (100) adapted to receive light emitted from a plurality of light sources (A, B), each of the plurality of light sources (A, B) emitting light comprising a light source identifier. The sensing device (100) comprises a sensing module (110) comprising a light selection unit (114) configured to receive at least a portion of the light emitted from the plurality of light sources (A, B) and a light selection unit (114) configured to receive at least a portion of the light emitted from the plurality of light sources (A, B). The light selection unit (114) is adapted to selectively convey a selected portion of light received by the light selection unit (114) to a second photo sensor unit (116). The light selection unit (114) is arranged relatively to the first photo sensor unit (112), or vice versa, in such a way that the selected portion of light is associated with a photo sensor of a plurality of photo sensors of the first photo sensor unit (114) detecting light.
