ABSTRACT:
In a signal transmission device as well as a method for transmission of signals between two elements moving relative to one another, in particular for transfer of measurement and/or control data between a rotating part and a stationary part of a computed tomography apparatus, a transmission device with an RF strip conductor is used on a first of the two elements, the RF strip conductor is composed of a dielectric layer with electro-optical properties between two strips made of an electrically-conductive material, into which the signals are fed. In the method and the associated device, local temporal changes of optical properties of the dielectric layer that are electrically induced in the dielectric layer by the signals proceeding along the strip conductor are scanned with a light beam of a scanning unit arranged on the second element, at least during a movement segment of the relative movement of the two elements. The signal transmission device and associated method enable signal transmission with a high data rate.
