Abstract

An apparatus and method for scanning ascertainment of a distance to an object are disclosed. Lasers of a light source emit a plurality of optical signals each having a time-varying frequency. At a given time, the frequencies of the optical signals are different. An evaluation device ascertains the distance to the object on the basis of measurement optical signals that were emitted by the light source and reflected or scattered at the object, and of reference optical signals that were emitted by the light source and were not reflected or scattered at the object. A dispersive scanning device simultaneously deflects the optical signals in different frequency-dependent directions.
