More Information
Summary:A device for a sending and receiving unit of a communication arrangement is provided. The device includes: a first passage for electromagnetic waves and a second passage for electromagnetic waves; a partially transparent surface which is transparent for electromagnetic waves of a first wave length range and which is reflective for electromagnetic waves of a second wave length range, wherein the second wave length range differs from the first wave length range; and a first retroreflective surface which is retroreflective for electromagnetic waves of the first wave length range. A direction of reflection of the electromagnetic waves of the first wave length range differs from a direction of reflection of the electromagnetic waves of the second wave length range if the electromagnetic waves of the first wave length range as well as the electromagnetic waves of the second wave length range are incoming through the same passage.
