Abstract
In an embodiment an optical measuring arrangement includes a tube section-shaped hollow body having a central axis extending from a first end face to an opposite second end face of the hollow body, wherein a spiral-shaped hollow light guide is formed in an inner surface of the hollow body by the inner surface being formed at least partially from a light-reflecting material and being formed as a hollow spiral winding around the central axis with a hollow cross section open toward the central axis, a light source arranged at a first spiral end and lying on the first end face of the hollow body, the light source configured to emit a light beam into the hollow spiral so that the light beam is tangentially to its turns and, after a plurality of reflections inside the hollow spiral, emerges from a second spiral end lying on the second end face of the hollow body and a light detector arranged at the second spiral end, the light detector configured to detect the emerging light beam and to output an electronic measurement signal as a function of the detected light beam.
