Definitions
- the invention relates to a device for transmitting information with optical signals between a transmitting and a receiving unit, which are movable relative to one another.
- the contour of the receiving unit is formed along the trajectory resulting from the relative movement of the transmitting unit and has at least one strand of material which converts the optical signals into fluorescent light.
- the material strand is connected to a detector unit, so that the optical signals impinging on the surface of the material strand cause fluorescent light signals within the material strand which are guided to a detector unit by way of an internal light guide.
- Optical information transmissions of the aforementioned type preferably occur on device parts which move relative to one another and between which a data exchange is to be made possible.
- radar systems may be mentioned which have rotating radar antennas which are rotatably mounted on a fixed substructure.
- the supply lines required for the operation of such systems, via which the power supply is made possible and the transmit and receive signals are conducted, are connected to one another at a separation point between the fixed and the rotating part via conventional slip ring contact tracks.
- optical slip ring systems which transmit information signals by way of light transmission between a light transmitter and a light receiver.
- Examples from medical technology in particular from the field of computed tomography, are known which, for example on a fixed device part which is arranged around a patient couch, has an optical fiber bent into a circle and connected at one end to a light detector unit. Opposite the optical fiber, a light-transmitting unit is arranged on a carrier ring rotating around the patient bed. The rotation of the carrier ring takes place in such a way that the light emitting unit always runs opposite the curved optical fiber. In this way, light signals can be received from the light receiving unit throughout the rotation be received without the kinematic properties of the Gesa taparatur being hindered by the data transmission.
- the optical fiber has fluorescent material which, when irradiated by the light transmission unit, generates fluorescent light within the fiber which is transmitted by the optical fiber.
- Generic receiving devices which provide optical fibers suitable for light absorption and for the generation of fluorescent light, which are mixed with fluorescent material and which are bent in accordance with the path courses over which the information signals are to be transmitted.
- this type of optical fiber arrangement has the disadvantage that the optical fiber is deformed mechanically to a large extent, particularly in places where there are large curvatures, so that high internal stresses occur in the fiber. Long-term operation with bent optical fibers in particular can lead to internal damage and breakage in the material. Complex repairs are the result, which sometimes interrupt the very costly operation of, for example, computer tomography systems.
- a device for transmitting information with optical signals between a transmitting and a receiving unit according to the preamble of claim 1 has a material strand for absorbing the optical information signals sent by the transmitting unit and forwarding the light signals converted by fluorescence effects to a corresponding one chenden detector unit, the contour of which is prefabricated in a suitably adapted manner to the path of the transmitter unit.
- the invention is based on the idea that the curved optical fiber known per se is replaced by a strand of material which has no internal stresses. points, since this is adapted to the required geometries by appropriate preprocessing.
- the contour of the strand of material is primarily based on the movement path or trajectory of the transmission unit, which can be curved or straight.
- a material strand according to the invention is to be worked out from a suitable surface material which has fluorescent properties in such a way that the material strand has an annular outer contour and a largely rectangular cross section.
- a suitable surface material which has fluorescent properties in such a way that the material strand has an annular outer contour and a largely rectangular cross section.
- Such a ring is to be introduced in this form into a correspondingly designed recess in a device part, which preferably consists of aluminum or copper and the recess has been worked out with a diamond tool.
- a highly reflective surface on the recess is obtained at the same time.
- the annular strand of material is to be inserted into this recess, so that it is at least partially surrounded by a highly reflective surface.
- the fluorescent light produced is reflected back into the material strand almost without loss, at least on the highly reflective surfaces, in order to reach a detector at a suitable point.
- a plurality of strands of material are to be arranged next to one another, which, separately from one another, enable a large number of information channels between two moving bodies.
