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.

A fiber optic rotary joint for coupling an optical signal across a rotary interface comprising: a stator, an annular reflective wall formed on said stator, a stator optic fiber mounted on said stator and having an end in close proximity and tangential to said annular reflective wall, a rotor, a rotor optic fiber, means on said rotor for positioning an end of said rotor optic fiber in close proximity and tangential to said annular reflective wall, whereby a signal emitted by one of said optic fibers will be projected tangentially against and reflected in short chordal paths along said annular reflective wall to be received by the other of said optic fibers.
