Patent ID: 8195051

Claim:
An apparatus comprising a rotating data transmission device for transmission of electrical signals between a first part and a second part of the apparatus, of which one of the parts is a rotating part and the other part is a stationary part, with the first part comprising: at least one data source for generating a digital data stream with a first optical transmitter; at least one first light-waveguide for transmitting the generated digital data stream from the at least one data source; at least one driver with a first optical receiver for receiving the digital data stream from the first light-waveguide; and a transmitting conductor arrangement controlled by the driver for receiving the data stream from the driver; and the second part comprising: a receiving coupler arrangement for tapping off signals from the transmitting conductor arrangement; at least one receiver for amplifying and processing signals received from the receiving coupler arrangement, and having a second optical transmitter; at least one second light-waveguide for transmitting the data stream from the receiver; and at least one data sink having at least one second optical receiver for receiving the data stream from the at least one second light-waveguide; and wherein at least one of the first optical receiver and the second optical receiver has at least one receiving element with an at least linear characteristic, an output signal of which is further processed via an equalizer that supplies a corrected frequency and phase of an analog signal to a digitizer.
