Abstract: A transmission unit of a LIDAR device. The transmission unit includes at least one beam source for generating electromagnetic beams having a linear or rectangular cross section, and transmission optics. The transmission unit has an optical homogenizer which is arranged in a beam path of the generated beams in front of or behind the transmission optics and has at least one lens array. A LIDAR device is also described.

Abstract: A cleaning unit for cleaning foreign matter from a cover, in particular a cover of a transmitter/receiver window of an environment sensor, including at least one movable wiper blade, which is arranged so as to wipe off foreign matter such as water or dirt on the cover by movement along the cover. For this purpose, the wiper blade touches the cover for example with one or multiple rubber lips. The wiper blade is positioned in an inclined manner with respect to a direction of movement of the wiper blade and is thus movable in such a way that a force exerted by the moved wiper blade on the foreign matter has a component in the direction of the force of gravity. Also described is a related device for sensing the environment as well as a method for cleaning a cover.

Abstract: A transmission unit for a LIDAR device for emitting collimated beams into a scanning area. The transmission unit includes at least one beam source for generating beams in the form of a beam bundle, the beam source being designed as a surface emitter or an emitter array, and a transmission optical unit including at least one lens. The transmission unit includes a diaphragm including at least one aperture, which is configured to delimit a cross section of the beam bundle of the generated beams in a horizontal direction and/or a vertical direction. The at least one lens of the transmission optical unit is situated downstream from the diaphragm in the emission direction of the beams. A LIDAR device is also described.

Abstract: A device which is designed to detect surroundings and which includes a housing and a sensor situated within the housing. The housing includes a transmitter/receiver window, through which the corresponding sensor signals may be emitted into the surroundings by the sensor, and/or sensor signals from the surroundings may be received. The device includes a cover, the cover being designed to be transparent to the sensor signals, and the cover being designed to cover the transmitter/receiver window against exterior surroundings of the device. The device includes a cleaning unit, which is situated at an outside of the housing and is movable relative to the housing using a drive unit. The cleaning unit is designed to remove contaminants from the cover. The cleaning unit includes at least one first nozzle to spray a cleaning liquid onto the cover, and at least one second nozzle to blow a gas onto the cover.

Abstract: A lidar sensor. The lidar sensor includes a light source and a fly eye lens arrangement having a first microlens arrangement and a second microlens arrangement. The first microlens arrangement comprises a plurality of identical first microlenses stacked along a first axis. The second microlens arrangement comprises a plurality of identical second microlenses stacked along a second axis. The fly-eye lens arrangement is configured to generate, based on a light generated by the light source, a scanning beam for scanning an environment of the lidar sensor. The scanning beam includes a first sub-beam generated by the first microlens arrangement and a second sub-beam generated by the second microlens arrangement. Predefined optical properties of the first microlens arrangement and predefined optical properties of the second microlens arrangement differ from one another in order to generate a scanning beam having a predefined light intensity distribution.
