Abstract
To enable signals to be transmitted from a fixed machine part to a machine part opposite same which rotates on a hollow shaft or vice versa, light must be able to be transmitted or received over the entire circumference. This is achieved by using an optical waveguide which, unlike conventional optical waveguides, is designed to couple out some of the light passing through it and, conversely, to allow light to enter, at any locations on its circumference.
