Abstract

An optical rotary joint (102) includes first (112) and second (114) hollow tubular members. At least one of the first (112) and second (114) hollow tubular members is rotatable about a common longitudinal axis. A ring shaped optical waveguide (113) between the first (112) and second (114) hollow tubular members includes first and second axial faces oriented perpendicular to the common longitudinal axis, an inner circumferential edge facing the outer circumference of the first hollow tubular member, an outer circumferential edge facing the inner circumference of the second hollow tubular member, and a circular light scattering channel (123) formed in the first and/or second axial faces. First optical emitters (116) are arranged to face the outer or inner circumferential edge. Second optical emitters (118) are arranged to face the channel (123). A first optical receiver (120) is arranged to face the outer or inner circumferential edge. A second optical receiver (122) is arranged to face the channel (123).
