Abstract

What is described here is a device for the transmission of modulated optical signals between two units supported for rotation relative to each other, by means of optical transmitters and receivers. The total of optical transmitters and receivers is three at minimum. A switching unit selects optical transmitters or receivers, respectively, for transmission in dependence on the position as well as in a synchronised manner so that the optical path will always have the same orientation as the direction of movement. Moreover, means are provided for suppressing multiply transmitted data.
