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.

Arrangement and method for using light signals and groups of light-receiving elements with different sensitivities to determine a distance of an object

An improved method for optical distance measurement is provided, in which only subsets of the transmitting elements of the transmission matrix are activated when using a transmission matrix to transmit measuring pulses and a reception matrix for receiving the latter.

Method and device for optically measuring distances

In order to improve the failure proneness of methods or devices for optically measuring distances, it is proposed that the measurement pulses for measuring distances are sent out aperiodically.
