Abstract: The invention relates to an optical rotary transmitter for transmitting optical signals, comprising a first light coupler (1) that has one or a plurality of first light guides (11) the end faces of which are designed to transmit optical signals and are arranged on a first ring about a central rotational axis Z, a second light coupler (3) that has one or a plurality of second light guides (31) the end faces of which are designed to transmit optical signals and are arranged on a second ring about the central rotational axis Z, a fiber mirror (5) comprising a plurality of third light guides that are arranged between said two light couplers (1,3) and are designed to compensate for the effect, on the transmission of the optical signals, of the two light couplers (1,3) rotating relative to one another, the end faces of the third light guides being designed to transmit optical signals and arranged on a third and fourth ring about the central rotational axis Z.

Abstract: An optical rotary transmitter which ensures the reliable transmission of optical signals in conjunction with a comparatively simple construction comprises two parts spaced apart from one another which are rotatable relative to one another about a common centre axis and the first of which comprises a first circular light coupler (10) and the second of which comprises a second circular light coupler (20). The light entrance and light exit surfaces of the two light couplers face one another. Each of the light couplers (10, 20) consists of collimators (11, 21) combined to form a respective collimator arrangement (16, 26), optical coupling elements (15, 25) being connected to said collimators.
