Claim 8:
9. The optical device according to claim 1, wherein the light path elements are formed by one or several optical fibers,
wherein each of the light path elements is at least partially limited radially inward and outward by a respective different one of the first interface and a second interface,
wherein the second interface of the light path elements are each configured to reflect light incident from the light path at an angle of incidence greater than a critical angle of the respective second interface onto the respective second interface to keep a light beam propagating along the light path in a predetermined direction of travel for the respective light path segment on the light path, and
wherein the light path elements are wedge-shaped and have a greater expansion in the radial direction at a first tangential end than at a second tangential end.
