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 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 LIDAR sensor for optically detecting a field of view. The LIDAR sensor includes an emission unit for emitting primary light into the field of view and a receiving unit for receiving secondary light, which was reflected and/or scattered in the field of view by an object. The emission unit includes: a light source for generating the primary light; a plate-shaped light guide optics including a beam exit for guiding the generated primary light; and at least one emission optics for emitting the guided primary light into the field of view. The receiving unit includes: at least one receiving optics for receiving secondary light; at least two optical fibers, each including a beam entrance for guiding the received secondary light; and at least one detector unit for detecting the guided secondary light. The emission optics and the receiving optics are situated coaxially to one another.
