Abstract

Novel optical position sensor which, when illuminated by a lightline produces an electrical signal containing information about where the lightline strikes the surface of the sensor in relation to its origin (10). The sensor is provided with two or more detectors (5, 6, 7, 8) with wedge-shaped light sensitive area. Said detectors are located with point symmetry in relation to the origin. Two of said detectors are inner detectors (5, 6) accurately measuring the position of the lightline and located on both sides of a symmetry line (9) being parallel to the measuring direction (x) and substantially at right angles to the lightline. When the sensor is used to sense a position of an object, the lightline strikes the two inner detectors (5, 6) which are so orientated that the signal from one increases and the signal from the other one decreases if the position sensor is laterally displaced in the measurement direction (x).
