Abstract
A light source emits light of a predefined wavelength onto a coupling-in region which has a coupling-in diffraction structure and couples the light into a carrier medium in the direction of a measurement region. The measurement region is a combination of an emission diffraction structure and a receiving diffraction structure. The emission diffraction structure extracts light which has been coupled into a measurement volume to be monitored for reflection at an object outside the carrier medium. The receiving diffraction structure couples the reflected light, which is incident on the receiving diffraction structure from outside the carrier medium, into the carrier medium in the direction of a detector region. The detector region has a detector diffraction structure that routes the light onto a detector apparatus. Then the detector apparatus determines a distance to the object from a time of flight of the light from the light source to the detector apparatus.
