Abstract

A LIDAR sensor for detecting an object within a sampling space, includes a sampling unit that includes a magnetic channel, a guide element, and a movable component that is situated within the magnetic channel and is movable along the guide element under control of a control method that uses a linear drive.

First claim

What is claimed is:

1 . A LIDAR sensor for detecting an object within a sampling space, the LIDAR sensor comprising:
a sampling unit that includes:
a magnetic channel;
a guide; and
a movable component that is situated within the magnetic channel and movable, under control of a linear drive, along the guide.

2 . The LIDAR sensor of claim 1 , wherein the guide is designed as a magnetic bearing.

3 . The LIDAR sensor of claim 2 , wherein the sampling unit also includes at least one permanent magnet.

4 . The LIDAR sensor of claim 1 , wherein the movable component is movable along the guide with oscillation.

5 . The LIDAR sensor of claim 1 , wherein the movable component is movable along the guide with resonant oscillation.

6 . The LIDAR sensor of claim 1 , wherein the guide includes magnetic springs at outer boundaries of the guide.

7 . The LIDAR sensor of claim 1 , wherein portions of the sampling unit are semicircular.

8 . The LIDAR sensor of claim 1 , wherein the magnetic channel and the guide are semicircular.

9 . The LIDAR sensor of claim 1 , further comprising:
a detector for receiving light, wherein the movable component includes at least one first reflective optical element configured to deflect onto the detector light that has been reflected from the object within the sampling space.

10 . The LIDAR sensor of claim 9 , wherein the detector is situated on a side of the sampling unit facing the sampling space.

11 . The LIDAR sensor of claim 9 , further comprising:
a light source for emitting light into the sampling space, wherein the movable component includes at least one second reflective optical element configured to deflect the light that is emitted from the light source into the sampling space.

12 . The LIDAR sensor of claim 1 , further comprising:
a light source for emitting light into the sampling space.

13 . The LIDAR sensor of claim 1 , further comprising:
a refractive element situated on a side of the sampling unit facing the sampling space.

14 . The LIDAR sensor of claim 1 , further comprising:
an optical filter situated on a side of the sampling unit facing the sampling space.

15 . A method for controlling a LIDAR sensor for detecting an object within a sampling space, the LIDAR sensor including a sampling unit, the method comprising:
controlling, with a linear drive, movement of a movable component of the sampling unit within a magnetic channel and along a guide.

16 . The method of claim 15 , wherein the guide is designed as a magnetic bearing, the method further comprising:
controlling the magnetic bearing with a bearing controller.

17 . The method of claim 16 , further comprising:
determining, with the bearing controller, a position of the movable component on the guide.
