Abstract:
1. A device for encoding a position of an object, comprising: a first light source; a first collimating element adapted to form first collimated light from the first light source, the first collimated light comprising a first collimated light beam; a carrier adapted to guide the first collimated light, the carrier comprising a first primary light redirecting structure and a second primary light redirecting structure; and a detector device for encoding the position of an object with respect to an active area of an encoding plane; wherein the first primary light redirecting structure is adapted to redirect at least a part of the first collimated light beam through the active area into the second primary light redirecting structure; and wherein the second primary light redirecting structure is adapted to redirect light received from the first primary light redirecting structure onto the detector device.
