Claim 4:
5. A method for multidimensional detection of objects in an observation area using a multipulse LIDAR system, the method comprising:
generating a transmission laser beam, via a transmitting device, in the form of a temporal sequence of single laser pulses, the transmission laser beam with each of the single laser pulses illuminating a detection area that is limited to a subsection of the observation area and that samples at least one sampling point;
generating a scanning movement of the transmission laser beam in a scanning direction, resulting in successive sampling of the entire observation area at multiple successive sampling points in the scanning direction;
receiving a reception laser beam, generated by reflection and/or scattering of the transmission laser beam on objects in the observation area, on a detection surface that includes a linear or matrix subdetector system made up of multiple subdetectors adjacently situated in a first direction of extension, the sampling point on the detection surface, instantaneously detected by the transmission laser beam, being imaged in the form of a pixel that is successively shifted along the linear or matrix subdetector system due to the scanning movement of the transmission laser beam;
grouping subdetectors whose positions correspond to the instantaneous position of the pixel to form a macropixel that is individually associated with the pixel; and
jointly evaluating the subdetectors associated with the macropixel;
wherein the transmitting device includes multiple laser sources whose detection areas are mutually orthogonal with respect to the scanning direction, the detection surface for each of the laser sources including a subdetector system that is individually associated with the laser source, the subdetector systems being mutually orthogonal with respect to the scanning direction.
