Abstract

A LIDAR sensor for detecting an object in the surroundings, and to a method for activating a LIDAR sensor, the LIDAR sensor including at least one transmitting unit for emitting electromagnetic radiation, at least one receiving unit for receiving electromagnetic radiation which was reflected by the object, at least one refractive element, which is at least partially pervious to the electromagnetic radiation, and a rotating unit, which includes at least the at least one refractive element, the at least one transmitting unit and the at least one receiving unit. The core of the invention is that the at least one refractive element includes at least one optical lens and a beam splitter for splitting the electromagnetic radiation, two focal planes being present. The at least one transmitting unit and the at least one receiving unit are positioned in at least one focal plane of at least one refractive element.
