Abstract

A vehicle LIDAR system, including: a solid-state laser having a brightness of at least 100 kW/(mm 2 sr), which is designed to emit laser pulses having a wavelength of at least 900 nm and a maximum power per laser pulse of at least 50 W; at least one movably situated mirror for deflecting the laser pulses in the direction of objects to be detected; a receiver for detecting the laser pulses reflected by the objects.

Claims (25)

1. A vehicle LIDAR system, comprising:

a solid-state laser having a brightness of at least 100 kW/(mm 2 sr), which is designed to emit laser pulses having a wavelength of at least 900 nm and a maximum power per laser pulse of at least 50 W;

at least one movably situated mirror to deflect the laser pulses in a direction of an object to be detected; and

a receiver to detect the laser pulses reflected by the object.

2. The vehicle LIDAR system as recited in claim 1 , wherein the solid-state laser is designed as a vertical cavity surface-emitting laser.

3. The vehicle LIDAR system as recited in claim 1 , wherein the mirror is movable in two different directions.

4. The vehicle LIDAR system as recited in claim 1 , wherein the at least one mirror includes two mirrors, which are each movable in a different direction.

5. The vehicle LIDAR system as recited in claim 1 , wherein the mirror is movable at least one of magnetically and piezoelectrically.

6. The vehicle LIDAR system as recited in claim 1 , wherein a diameter of the mirror is greater than or equal to 1 mm.

7. The vehicle LIDAR system as recited in claim 1 , wherein a diameter of the mirror is greater than or equal to 3 mm.

8. The vehicle LIDAR system as recited in claim 1 , wherein the mirror is movable across at least an angle of 20°.

9. The vehicle LIDAR system as recited in claim 1 , wherein the mirror is movable across at least an angle of 30°.

10. The vehicle LIDAR system as recited in claim 1 , wherein the mirror has a reflectivity of at least 80%.

11. The vehicle LIDAR system as recited in claim 1 , wherein the mirror has a reflectivity of at least 90%.

12. The vehicle LIDAR system as recited in claim 1 , wherein the mirror is a microelectromechanical mirror.

13. A vehicle LIDAR system for detecting objects in surroundings of a vehicle, the vehicle LIDAR system comprising:

a solid-state laser having a brightness of at least 100 kW/(mm 2 sr), which is designed to emit laser pulses having a wavelength of at least 900 nm and a maximum power per laser pulse of at least 50 W;

at least one movably situated mirror to deflect the laser pulses in a direction of an object to be detected, the object being in the surroundings of the vehicle; and

a receiver to detect the laser pulses reflected by the object.

14. The vehicle LIDAR system as recited in claim 1 , wherein a diameter of the mirror is between 3 mm and 5 mm.

15. The vehicle LIDAR as recited in claim 13 , wherein a diameter of the mirror is between 3 mm and 5 mm.

16. The vehicle LIDAR system as recited in claim 1 , wherein a duty cycle of the laser pulses emitted by the solid-state laser is between 1% and 2%.

17. The vehicle LIDAR system as recited in claim 13 , wherein a duty cycle of the laser pulses emitted by the solid-state laser is between 1% and 2%.

18. The vehicle LIDAR system as recited in claim 1 , wherein the laser pulses emitted by the solid-state laser each has a pulse duration of less than 1 ns.

19. The vehicle LIDAR system as recited in claim 13 , wherein the laser pulses emitted by the solid-state laser each has a pulse duration of less than 1 ns.
