Method for improved near and remote detection of a LIDAR receiving unit
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.
1. Method for an improved near and remote detection at a LIDAR receiving unit,
wherein the receiving unit has a plurality of sensor elements,
wherein a macro cell has at least one first readout cell and one second readout cell,
wherein the first readout cell has at least one first sensor element, which is connected to a first readout element and
wherein the second readout cell has at least one second sensor element, which is connected to a second readout element, wherein
wherein at a first point in time within a measurement cycle at least a subset of readout cells on the active macro cell is activated,
wherein at a second point in time within the measurement cycle, which occurs after the first point in time, one readout cell is activated and/or one readout cell is deactivated.
2. Method according to claim 1 , wherein the time interval between the first point in time and the second point in time is between 50 to 500 nanoseconds long, in particular 200 nanoseconds.
3. Method according to claim 1 , wherein a potentially incident laser light undergoes a displacement at the receiving unit over the duration of the measurement cycle, wherein the readout cells form an active region and are activated and/or deactivated in such a manner that the active region follows this displacement.
4. LIDAR measuring system, which uses a method for an improved near and remote detection at a LIDAR receiving unit,
wherein the receiving unit has a plurality of sensor elements,
wherein a macro cell has at least one first readout cell and one second readout cell,
wherein the first readout cell has at least one first sensor element, which is connected to a first readout element and
wherein the second readout cell has at least one second sensor element, which is connected to a second readout element, wherein
wherein at a first point in time within a measurement cycle at least a subset of readout cells on the active macro cell is activated,
wherein at a second point in time within the measurement cycle, which occurs after the first point in time, one readout cell is activated and/or one readout cell is deactivated.
