Abstract
An optical encoder device () comprises: an optical emitter () for emitting light, the optical emitter () having a light emission direction (E); an optical detector () for detecting light emitted by the optical emitter (), the optical detector () having a light detection direction (D) which is different from the light emission direction (E); an optical element () for controlling an optical path () between the optical emitter () and the optical detector () such that light emitted by the optical emitter () can be detected by the optical detector (); and a free area () in the optical encoder device () for accommodating a moveable optical encoding unit () comprising a plurality of alternating transparent and opaque encoding elements such that the plurality of alternating transparent and opaque encoding elements of the optical encoding unit () is able to affect the optical path ().
