Abstract

Various implementations disclosed herein include a distance measuring unit for measuring, on the basis of a time-of-flight signal, a distance to an object situated in a detection field. The distance measuring unit includes an emitter unit for emitting pulses in the form of electromagnetic radiation, and a receiver unit comprising a sensor area for receiving the electromagnetic radiation in the form of echo pulses, and a mirror unit disposed upstream of the sensor area, wherein a detection field of the receiver unit is subdivided into a plurality of receiver solid angle segments, and wherein the plurality of receiver solid angle segments are assigned to the same sensor area in that echo pulses incident on the mirror unit from a respective receiver solid angle segment are reflected onto the sensor area when the mirror unit is in a tilt state associated with the respective receiver solid angle segment.
