DEVICE, SYSTEM AND METHOD OF ENCODING POSITION OF OBJECT

摘要

PROBLEM TO BE SOLVED: To provide a device, system and method of encoding an object position.SOLUTION: The present invention relates to the device for encoding a position of an object. The device comprises a first light source; a first collimating element adapted to form first collimated light from the first light source; a carrier adapted to guide light and comprising a first primary light redirecting structure and a second primary light redirecting structure; and a detector device for encoding a position of an object with respect to an active area of an encoding plane. The first primary light redirecting structure is adapted to redirect at least a part of a first light beam through the active area into the second primary light redirecting structure, and the second primary light redirecting structure is adapted to redirect the light received from the first primary light redirecting structure onto the detector device. Thereby, a collimated light beam propagates along the carrier and from the carrier into the active area via the first primary light redirecting means.
