Zusammenfassung:To improve LIDAR measurements in terms of accuracy and usability, the present invention provides a LIDAR arrangement (10) comprising a laser transmitter (12) for transmitting pulses of a laser radiation to a measurement object (40), and a receiver (13) for receiving pulses of the laser radiation backscattered from the measurement object (40), wherein the laser transmitter (12) is designed for transmitting a pulse sequence in which successive pulses respectively comprise a particular optical frequency shift to each other and wherein the receiver (13) 1.1 includes a dispersive element (16) for separating the pulses in time depending on the optical frequency by a frequency-based deflection, and a position resolution optical matrix transmitter (39) on which the pulses separated in time by the dispersive element are mapped, or 1.2 includes a frequency analyzer (60) for the frequency-based separation of the pulses by superimposition with a reference radiation.
