Abstract: A scanning-system including transmit/receive paths, a transmitter, a receiver and a rotating-scanning-device. The transmitter emits radiation which propagates along an optical-axis on the transmit-path. The radiation from the target-object is detected by the receiver on the receive-path. The rotating-scanning-device includes an optical-system and a rotating-deflection-unit, which deflects the radiation of the transmit/receive paths. The optical-system includes a first-focusing-unit and a rotating-second-focusing-unit. The movements of the rotating-deflection-unit and the rotating-second-focusing-unit occur synchronously to ensure an alignment of the deflected radiation with the second-focusing-unit. The first-focusing-unit reproduces the radiation emitted by the transmitter on the rotating-deflection-unit so that the beam-diameter on the rotating-deflection-unit is reduced.

Abstract: A method for the supplementary detection of objects by a LIDAR system. The LIDAR system is configured to scan a solid angle range to carry out a primary distance determination method for surroundings objects. An emitter unit emits at least one laser beam in a solid angle strip of the solid angle range, laser light reflected from surroundings objects being received by a detector unit to ascertain the distance and the position of surroundings objects with the aid of the primary distance determination method. The method includes: scanning the entire solid angle range and subsequently generating a two-dimensional intensity distribution of the detected signal light. This is followed by generating a corrected two-dimensional intensity distribution by removing blooming signals and analyzing the corrected two-dimensional intensity distribution for the supplementary detection of surroundings objects in addition to the primary distance determination method.
