  • Fiber optic rotary joint using a reflective surface and tangentially mounted rotor and stator optical fibers
    Patent number: 4525025
    Abstract: A fiber optic rotary joint which couples an optical signal across a rotary interface includes an annular reflective wall formed on a stator and an optic fiber mounted on the stator having one end in close proximity to the annular reflective wall. A rotor includes a rotor optic fiber which has one end positioned in close proximity and tangential to the annular reflective wall. A signal emitted by one of the optic fibers will be reflected in short chordal paths along the annular reflective wall and received by the other of the optic fibers.
