Abstract
A device for receiving data from a rotatable source includes a primary winding of a rotary transformer fixed to a support structure and connected to an electric power source. A secondary winding is rotatably supported by the support structure. An axial passage extends through the primary and secondary windings. An optical data transmitter is connected to the secondary winding. The optical data transmitter is rotatably supported by the support structure and aligned to transmit data through the axial passage in the rotary transformer. The secondary transformer winding provides power to the optical data transmitter without physical contact. An optical data receiver fixed to the support structure receives data from the optical data transmitter transmitted through the axial passage in the rotary transformer without physical contact. The transmission of power and data without physical contact allows the data source to rotate continuously.
