<p>The invention, useful in computer tomography, relates to an optical transmission arrangement for transmitting data between two relatively rotatable parts. The invention utilizes a hollow cylinder with a mirrorcoated 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, which can be smaller as the angle is smaller at which the light is incident onto the inner surface. In this case, there is obtained on the one hand a small pulse widening and on the other hand a comparatively low damping because the reflecting power at small angles of incidence is constantly comparatively high.</p> |
