1. A reflex coupler, comprising:
- an organic light emitter arranged to emit a light signal; and
an inorganic photodetector which comprises a detector area;
whereinthe light emitter and the detector area can be coupled optically as a result of radiation returned from an object onto which the light signal impinges, and the organic light emitter and the inorganic photodetector are integrated in one device;
the reflex coupler includes further organic light emitters and/or further inorganic photodetectors;
the further organic light emitters and/or the further inorganic photodetectors are arranged across an area or along a direction, and the inorganic photodetector and the further inorganic photodetectors are arranged so as to be able to independently detect reflections on the object or on further objects; and
the inorganic photodetector and the further inorganic photodetectors are arranged in at least one direction; and
the reflex coupler includes an evaluating unit which is arranged so that a relative movement of the object to several of the inorganic photodetector and the further inorganic photodetectors in the at least one direction can be determined and a velocity of the object can be determined from a pulse frequency of an output signal.

Abstract
A reflex coupler has an organic light emitter for generating a light signal and an inorganic photodetector with a detector area. The organic light emitter and the detector area are optically coupled as a result of radiation returned from an object onto which the light signal impinges, and the organic light emitter and the inorganic photodetector are integrated in one device.
