摘要： Method for the improved near and remote detection of a LIDAR receiving unit for motor vehicles, wherein the receiving unit has a plurality of sensor elements, wherein the sensor elements can be activated and deactivated, wherein at least a subset of the sensor elements are activated at a first point in time within a measurement cycle, wherein one or more sensor elements are activated and/or one or more sensor elements are deactivated at a second point in time within the measurement cycle, said second point in time occurring after the first point in time.

摘要： The invention relates to an assembly or a method for ascertaining the distance to at least one object. The 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 first electric signals are used to ascertain the distance 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 by means of an additional signal processing which differs from the time-correlated photon counting process. The second group has a lower degree of sensitivity for converting the photons into an electric current than the first group.

摘要： A receiving arrangement for receiving light signals and a method for receiving light signals are proposed, wherein a light receiver is provided, which serves for receiving the light signals and converting them into electrical signals. Furthermore, an evaluation circuit is provided, which, depending on the electrical signals and a start signal for the emission of the light signals, determines a distance between the receiving arrangement and an object at which the light signals are reflected. A characterizing feature is that the light receiver has a first group of light-receiving elements, which has a higher sensitivity for receiving the light signals than at least one further group of light-receiving elements, wherein the first and the further groups are ready for reception at different times.

摘要： A method for optical distance measurement is proposed which comprises the emission of a plurality of measurement pulses, the reflection of emitted measurement pulses at at least one object and the receipt of reflected measurement pulses. A sequence of measurement pulses is emitted, wherein the sequence comprises temporal pulse spacings between temporally successive measurement pulses, and wherein each measurement pulse of the sequence has a temporal pulse width of T(Pulse). The pulse spacings form a first set, wherein the first set is defined by {T(delay)+i*T(Pulse): i is an element of the natural numbers between 0 and j}, wherein for all values of i it holds that: T(delay)+i*T(Pulse)
