Abstract

A method for detecting objects using a LIDAR system. The method includes emitting a first light beam scanning in a scanning direction in an emission direction at a first instant, allocating a first propagation time between the first transmission instant and a first receiving instant of a first reflection of the first light beam to the emission direction, emitting in the emission direction, an angle-resolved, further light beam scanning in the scanning direction and angularly offset from the first light beam, at a second transmission instant following the first emission instant, allocating a second propagation time between the second transmission instant and a second receiving instant of a second reflection of the second light beam to the emission direction, and evaluating hits using the propagation times allocated to the emission direction.
