Abstract

LIDAR measurement system with a LIDAR transmitting unit and a LIDAR receiving unit, which is configured in a focal-plane-array arrangement, wherein the LIDAR receiving unit has a plurality of sensor elements and wherein the LIDAR transmitting unit has a plurality of emitter elements, wherein a plurality of sensor elements form a macrocell, wherein the macrocell is associated with a single emitter element, wherein the distance between two adjacent emitter elements is unequal to an integer multiple of the distance between two adjacent sensor elements.

Claims (36)

1. A LIDAR measurement system with a LIDAR transmitting unit and a LIDAR receiving unit, which is configured in a focal-plane-array arrangement, wherein

the LIDAR receiving unit has a plurality of sensor elements and wherein

the LIDAR transmitting unit has a plurality of emitter elements, wherein

a plurality of sensor elements form a macrocell, wherein the macrocell is associated with a single emitter element,

wherein the distance between two adjacent emitter elements is unequal to an integer multiple of the distance between two adjacent sensor elements.

2. The LIDAR measurement system according to claim 1 , wherein

the emitter elements and the macrocells are respectively arranged apart in a row-column arrangement and wherein

the sensor elements are likewise arranged in a row-column arrangement.

3. The LIDAR measurement system according to claim 1 , wherein adjacent sensor elements of an odd order have an offset and adjacent sensor elements of an even order have no offset.

4. The LIDAR measurement system according claim 1 , wherein sensor elements that are adjacent column-wise have a row-wise offset.

5. The LIDAR measurement system according to claim 1 , wherein sensor elements that are adjacent in the row direction have an offset oriented in the column direction.

6. The LIDAR measurement system according to claim 1 , wherein the columns of emitter elements of the LIDAR transmitting unit and the columns of sensor elements of the LIDAR receiving unit are configured so as to be parallel to one another or have an angle α relative to one another.

7. The LIDAR measurement system according to claim 6 , wherein in that the angle α lies between 0° and 45°.

8. The LIDAR measurement system with a LIDAR transmitting unit and a LIDAR receiving unit, which is configured in a focal-plane-array arrangement, wherein

the LIDAR receiving unit has a plurality of sensor elements and wherein

the LIDAR transmitting unit has a plurality of emitter elements, wherein

a plurality of sensor elements form a macrocell, wherein the macrocell is associated with a single emitter element, wherein

the emitter elements and the macrocells are respectively arranged apart in a row-column arrangement and wherein

the sensor elements are likewise arranged in a row-column arrangement,

wherein the number of rows of sensor elements ( 26 ) of a plurality of adjacent macrocells is unequal to the integer multiple of the associated emitter elements.

9. The LIDAR measurement system according to claim 8 , wherein adjacent sensor elements of an odd order have an offset and adjacent sensor elements of an even order have no offset.

10. The LIDAR measurement system according to claim 8 , wherein sensor elements that are adjacent column-wise have a row-wise offset.

11. The LIDAR measurement system according to claim 8 , wherein sensor elements that are adjacent in the row direction have an offset oriented in the column direction.

12. The LIDAR measurement system according to claim 8 , wherein the columns of emitter elements of the LIDAR transmitting unit and the columns of sensor elements of the LIDAR receiving unit are configured so as to be parallel to one another or have an angle α relative to one another.

13. The LIDAR measurement system according to claim 12 , wherein the angle α lies between 0° and 45°.

14. The LIDAR measurement system with a LIDAR transmitting unit and a LIDAR receiving unit, which is configured in a focal-plane-array arrangement, wherein

the LIDAR receiving unit has a plurality of sensor elements and wherein

the LIDAR transmitting unit has a plurality of emitter elements, wherein

a plurality of sensor elements form a macrocell, wherein the macrocell is associated with a single emitter element, wherein

the emitter elements and the macrocells are respectively arranged apart in a row-column arrangement and wherein

the sensor elements are likewise arranged in a row-column arrangement, having a number of rows of N emitter elements and associated N macrocells, wherein the number of rows of sensor elements of the N macrocells is determined by (m·N)+k, wherein m is an integer and k is an integer between 1 and N−1.

15. The LIDAR measurement system according to claim 14 , wherein adjacent sensor elements of an odd order have an offset and adjacent sensor elements of an even order have no offset.

16. The LIDAR measurement system according to claim 14 , wherein sensor elements that are adjacent column-wise have a row-wise offset.

17. The LIDAR measurement system according to claim 14 , wherein sensor elements that are adjacent in the row direction have an offset oriented in the column direction.

18. The LIDAR measurement system according to claim 14 , wherein the columns of emitter elements of the LIDAR transmitting unit and the columns of sensor elements of the LIDAR receiving unit are configured so as to be parallel to one another or have an angle α relative to one another.

19. The LIDAR measurement system according to claim 18 , wherein the angle α lies between 0° and 45°.
