Abstract
Official abstract text for this publication.
A coaxial LiDAR system having a reduced adjustment complexity and reduced installation space includes a transmitter unit designed to emit LiDAR radiation, a receiver unit designed to detect incident LiDAR radiation, and an optical system for imaging LiDAR radiation, the radiation emitted by the transmitter unit and the radiation from the optical system incident upon the receiver unit being transmitted in collinear form, the emitting surface of the transmitter unit being situated outside of the focus of the imaging optical system.
First claim
Opening claim text (preview).
What is claimed is: 1. A LiDAR system, comprising: a transmitter including an emitting surface, wherein the transmitter is configured to emit LiDAR radiation via the emitting surface; a receiver configured to detect incident LiDAR radiation; and an optical system configured to transmit in collinear form the radiation emitted by the transmitter and the radiation incident upon the receiver; wherein the emitting surface of the transmitter is situated outside of a focus of the optical system, and wherein a plane of at least one detection surface of the receiver lies along a longitudinal axis, which is perpendicular to the detection surface and the emitting surface, and wherein the emitting surface of the transmitter lies along the longitudinal axis, which is perpendicular to the plane of the at least one detection surface and the emitting surface. 2. The LiDAR system of claim 1 , wherein the at least one detection surface of the receiver is situated at the focus of the optical system. 3. The LiDAR system of claim 1 , wherein the at least one detection surface of the receiver is situated outside of the focus of the optical system. 4. The LiDAR system of claim 1 , wherein a distance between the emitting surface and the optical system is greater or smaller than a distance between the at least one detection surface of the receiver and the optical system. 5. The LiDAR system of claim 1 , wherein a distance between the emitting surface and the optical system is equal to a distance between the at least one detection surface of the receiver and the optical system. 6. The LiDAR system of claim 1 , wherein the at least one detection surface of the receiver is larger than the emitting surface of the transmitter. 7. The LiDAR system of claim 6 , wherein the at least one detection surface includes a passband for transmission of LiDAR radiation. 8. The LiDAR system of claim 6 , wherein the at least one detection surface includes a plurality of detection surfaces of a plurality of individual detectors. 9. The LiDAR system of claim 1 , wherein an optical path from the transmitter to the optical system includes a deflecting device. 10. The LiDAR system of claim 1 , wherein an optical path from the transmitter to the optical system includes an intermediate optical system. 11. The LiDAR system of claim 1 , wherein the optical path from the optical system to the receiver includes a deflecting device. 12. The LiDAR system of claim 1 , wherein the optical path from the optical system to the receiver includes an intermediate optical system.
