Abstract: A functionalized waveguide for a detector system includes an incoupling region of a main body that deflects only part of the radiation coming from an object to be detected and impinges on the front face such that the deflected part propagates as coupled-in radiation in the main body by reflections up to the decoupling region and impinges on the decoupling region. A decoupling region deflects at least part of the coupled-in radiation impinging thereon such that the deflected part exits the main body via the front or rear face to impinge on the detector system. The extent of the incoupling region in a second direction transverse to the first direction is greater than the extent of the decoupling region in the second direction. In the second direction, the incoupling region has at least two different diffractive incoupling structures which have a different deflection component in the second direction.
