Abstract:
1. An optical coupling apparatus for optically coupling a first, rotationally moveable optical component with a second, non-rotating optical component to enable an optical signal to be transmitted between said first and second optical components, said apparatus comprising: a first annular member for supporting an outer most end of said first optical component in at least a partial circular arrangement; a second annular member for supporting an outer most end of said second optical component in at least a partial circular arrangement, said first and second annular members being longitudinally aligned with one another along a longitudinal axis; wherein a face portion of each of said annular members are placed in facing relationship to enable said first, rotationally moveable optical component to be optically coupled to said second non-rotating optical component without physical contact therebetween; and a coupling structure extending within both of said annular members to maintain said annular members longitudinally aligned with said longitudinal axis.
