Abstract
Data is to be exchanged between a rotating element and a further element, with the rotating element being rotated by way of a hollow shaft. Light is coupled into torus halves and is reflected into a torus half and onto torus inner walls so often by way of a small opening until it exits at an opening of the other torus half. In a first embodiment, a torus-shaped optical fiber is divided into two torus halves. In another embodiment, hollow tori are used, which are filled with a fluid, namely either with a liquid or with air.
