Abstract

Claims (36)

1. A method for identifying at least one object having a connection unit that can be connected to a receptacle unit of a receptacle arrangement, wherein contactless, optical information transfer takes place between the connection unit and the receptacle unit if the connection unit is connected to the receptacle unit, the method comprising:

generating and transmitting an optical signal having predetermined optical properties using at least one transmitting unit, the predetermined optical properties including a predetermined polarization value;

transferring the optical signal via at least one optical transfer path;

receiving the optical signal with at least one receiving unit;

evaluating properties of the received optical signal with an evaluation and control unit connected to the receiving unit, the evaluated properties including a polarization value; and

identifying the object by comparing the polarization value with the predetermined polarization value;

wherein the transmitting unit is arranged on a connection unit side or on a receptacle unit side and the receiving unit is arranged on the connection unit side or on the receptacle unit side.

2. The method as claimed in claim 1 , wherein an optical transfer path influences a propagation time of the optical signal in a predetermined manner.

3. The method as claimed in claim 2 , wherein at least one transmitting unit and at least one receiving unit are arranged on the receptacle unit side and the connection unit comprises an identification unit, wherein the optical signal is transferred via a transmission path from the transmitting unit to the identification unit and via a reception path from the identification unit to the receiving unit, wherein at least the identification unit influences the optical properties and/or the propagation time of the optical signal.

4. The method as claimed in claim 3 , wherein the receptacle unit comprises an identifying unit, wherein the optical signal is transferred via a first partial transmission path from the transmitting unit to the identifying unit, via a second partial transmission path from the identifying unit to the identification unit, via a first partial reception path from the identification unit to the identifying unit and via a second partial reception path from the identifying unit to the receiving unit.

5. The method as claimed in claim 2 , wherein the transmitting unit is arranged on the connection unit side and the receiving unit is arranged on the receptacle unit side, wherein the connection unit comprises an identification unit and/or the receptacle unit comprises an identifying unit, wherein the identification unit and/or the identifying unit influence the optical properties and/or the propagation time of the optical signal.
