Patent ID: 7280714

Claim:
A device for optoelectronically detecting movement and/or position of an object comprising at least one transmitting element for emitting radiation in the optical wavelength range and at least one receiving element for receiving at least a part of the radiation emitted by the transmitting element and reflected back by the object and also comprising an optical guide arranged in the beam path between the transmitting element and the receiving element, wherein the optical guide comprises at least one light coupling element for at least one of: coupling-in the radiation previously radiated through the optical guide and diffusely scattered at the object transversely to a longitudinal extent of the optical guide, and coupling-out radiation radiated to the optical guide by the transmitting element transversely to the longitudinal extent of the optical guide, wherein the at least one transmitting element and/or the at least one receiving element are arranged at the edge of the optical guide spaced from the light coupling element.
