Lidar Sensor for a Vehicle, Having a Receiving Element for Focusing in a Focal Point Region, Vehicle Comprising a Lidar Sensor, and Method for Operating a Lidar Sensor

A lidar sensor for a vehicle, the lidar sensor comprising:

• an optical emitting unit for scanning surroundings of the vehicle within a predetermined sensing region by individual laser beams;
• an optical receiving unit comprising a receiving element for receiving the individual laser beams reflected by the surroundings and a detector for converting the reflected individual laser beams into an electrical signal;
• and
• an evaluation unit for determining a representation of the surroundings in the sensing region based on the electrical signal, wherein:
• the receiving element comprises at least one optical lens, wherein the at least one optical lens is configured to focus the individual laser beams reflected by the entire sensing region to the at least one optical lens in a predetermined focal point region, and
• the detector is configured to convert the individual laser beams focused in the focal point region into the electrical signal.

A method for operating a lidar sensor of a vehicle, the method comprising:

• scanning surroundings of the vehicle within a predetermined sensing region by individual laser beams by using an optical emitting unit;
• receiving the individual laser beams reflected by the surroundings and converting the reflected individual laser beams into an electrical signal by an optical receiving unit;
• and
• determining a representation of the surroundings in the sensing region based on the electrical signal by an evaluation unit, wherein:
• the individual laser beams reflected by the entire sensing region are focused in a predetermined focal point region by at least one optical lens of the receiving element, and
• the individual laser beams focused in the focal point region are converted by a detector into the electrical signal.
