Claim 8:
9. 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 multiple sampling points are simultaneously detected during an individual measurement, subdetectors that are detected by a first pixel that is generated by a first sampling point on the detection surface being associated with a first macropixel that is individually associated with the first sampling point, and subdetectors that are detected by a second pixel that is formed by a second sampling point on the detection surface being associated with a second macropixel that is individually associated with the second sampling point, and
wherein subdetectors that are detected by the first pixel during a first individual measurement and detected by the second pixel in a second individual measurement that takes place using a second single laser pulse immediately following the first single laser pulse are associated with the first macropixel for the first individual measurement, and with the second macropixel for the subsequent second individual measurement.
