A method for scanning solid angles is provided using at least two electromagnetic beams, at least one electromagnetic beam being generated that is subsequently deflected along a horizontal angle and/or along a vertical angle with the aid of a rotatable mirror; the solid angles being scanned using the at least one electromagnetic beam; and at least one reflected electromagnetic beam being received, after being reflected off an object, by a receiving optics that is pivotable along the horizontal angle synchronously with the mirror. Furthermore, a LIDAR device for carrying out the method is provided.

Method and device for scanning a solid angle

An optical assembly for a LiDAR system is described. The optical assembly includes receiver optics and transmitter optics, designed to include partially coaxial beam paths; a line light source having a line orientation, which is configured, in particular within the range of a field of view of the underlying LiDAR system; and a deflection unit in a transition region from a common coaxial region to a separate biaxial region of the beam paths of the receiver optics and of the transmitter optics for biaxially splitting off a detector-side portion of the beam path of the receiver optics. The deflection unit has a hole mirror having an elongated hole that has a greater extent in a direction of longitudinal extent and a lesser extent in a direction of transverse extent. The direction of longitudinal extent of the elongated hole is oriented orthogonally to the line orientation of the line light source.

An optical system for detecting a scanning field, a system for controlling the optical system as well as a method for controlling the optical system, the optical system having at least one transmitter comprising at least one source for emitting electromagnetic radiation and at least one deflection unit for deflecting the beam path of the electromagnetic radiation emitted by the source into the scanning field.
