Abstract
Light signals are converted into first electric signals by a first group of light-receiving elements, and the light signals are additionally converted into second electrical signals by a second group of light-receiving elements. The second group has a lower degree of sensitivity for converting the photons into an electric current than the first group. The first electric signals are used to ascertain the distance to an object by means of a time-correlated photon counting process depending on a starting time for the emission of the light signals. Furthermore, the second electric signals are used to determine the distance depending on the starting time but using a second signal processing different from the process used for the first electric signals.
