An optical transmission system arrangement for transmitting data between two relatively rotatable parts. A hollow cylinder with a mirror-coated inner surface onto which the light is incident at the smallest possible grazing angle and is frequently reflected. The light is coupled in and out through a coupling section in the hollow cylinder, at which the light is incident onto the inner surface. The system achieves a comparatively low damping because the reflecting power at small angles of incidence is comparatively high. |
