Abstract

A scanning device includes a transmitter, a receiver, and a rotor that is configured to be mounted in a rotatable manner about an axis of rotation. The transmitter is configured to at least occasionally emit electromagnetic radiation, and the receiver is configured to sense at least part of the electromagnetic radiation reflected and/or scattered by an object. The transmitter and the receiver are arranged on the rotor in an at least partially axially overlapping manner based on the axis of rotation.

First claim

The invention claimed is:

1. A scanning device, comprising:
a transmitter configured to emit electromagnetic radiation at least intermittently;
a receiver configured to capture at least a fraction of the electromagnetic radiation that is one or more of reflected and scattered by an object;
a rotor configured to be supported so as to be rotatable about a rotation axis; and
a drive motor with at least one member configured to generate a torque, the member arranged in an at least partly axially overlapping manner in relation to one or more of the transmitter and the receiver,
wherein the transmitter and the receiver are arranged on the rotor in an at least partly axially overlapping manner with respect to the rotation axis,
wherein the member is supported so as to be rotatable about a further rotation axis, the rotor coupled with the member in a torque-locked manner by a torque-locked connection.

2. The scanning device as claimed in claim 1 , wherein the transmitter, the receiver, and the member are arranged together on the rotor.

3. The scanning device as claimed in claim 1 ,
wherein the torque-locked connection includes a first tooth system coupled with the member, and a second tooth system coupled with the rotor,
wherein the first tooth system engages in a meshing manner with the second tooth system,
and/or
wherein the torque-locked connection includes at least one first disk coupled with the member in a torque-locked manner, and a second disk coupled with the rotor in a torque-locked manner, and a coupling member,
wherein the first disk is coupled by the coupling member with the second disk for the transmission of torque between the rotor and the member,
and/or
wherein the torque-locked connection includes an impeller coupled with the member, and a turbine wheel coupled with the rotor, wherein the impeller is coupled fluid-dynamically with the turbine wheel,
and/or wherein the torque-locked connection couples the rotor with the member inductively.

4. The scanning device as claimed in claim 3 , wherein the coupling member is configured as a chain or a belt, and wherein the impeller is coupled one or more of gas-dynamically and hydrodynamically with the turbine wheel.

5. The scanning device as claimed in claim 1 ,, wherein the rotation axis and the further rotation axis are arranged parallel to one another.

6. The scanning device as claimed in claim 1 , wherein the member includes at least one coil and/or a permanent magnet and/or an array of coils and/or an array of permanent magnets.

7. The scanning device as claimed in claim 1 , wherein the electromagnetic radiation has a frequency with a value lying within one or more of a range from 300 MHz to 130 GHz and a range from 384 THz to 789 THz.

8. A scanning device, comprising:
a transmitter configured to emit electromagnetic radiation at least intermittently;
a receiver configured to capture at least a fraction of the electromagnetic radiation that is one or more of reflected and scattered by an object;
a rotor configured to be supported so as to be rotatable about a rotation axis; and
a drive motor with at least one member configured to generate a torque, the member arranged in an at least partly axially overlapping manner in relation to one or more of the transmitter and the receiver,
wherein:
the transmitter, the receiver, and the member are arranged together on the rotor,
the transmitter and the receiver are arranged on the rotor in an at least partly axially overlapping manner with respect to the rotation axis,
the drive motor includes a stator,
the stator is arranged in an at least partly axially overlapping manner in relation to one or more of the transmitter and the receiver, and
the stator is arranged, at least in some sections, radially between the member and the transmitter and/or the receiver.

9. The scanning device as claimed in claim 8 , wherein the member includes at least one coil and/or a permanent magnet and/or an array of coils and/or an array of permanent magnets.

10. The scanning device as claimed in claim 8 , wherein the electromagnetic radiation has a frequency with a value lying within one or more of a range from 300 MHz to 130 GHz and a range from 384 THz to 789 THz.

11. A scanning device, comprising:
a transmitter configured to emit electromagnetic radiation at least intermittently;
a receiver configured to capture at least a fraction of the electromagnetic radiation that is one or more of reflected and scattered by an object;
a rotor configured to be supported so as to be rotatable about a rotation axis; and
a drive motor with at least one member configured to generate a torque, the member arranged in an at least partly axially overlapping manner in relation to one or more of the transmitter and the receiver,
