Abstract

A lidar device having an integrated optics that has a beam deflecting unit having an optical phase array that has a multiplicity of antennas that are set up to emit electromagnetic radiation at a prespecified angle of radiation. The angle of radiation covers a prespecified field of view of the lidar device. The angle of radiation has a first angle of radiation subregion, in which electromagnetic radiation is emitted having a polarization A, and has a second angle of radiation subregion, in which electromagnetic radiation is emitted having a polarization B.
