Abstract
The present invention is directed to segmented waveguide for a fiber optic rotary joint. The segmented waveguide is mountable to the existing stator surface. The segmented waveguide is capable of receiving signals from the rotor. The fiber optic rotary joint includes a rotor and an existing stator surface. The rotor is rotatable through a full 360° and is concentric to the existing stator surface. The rotor has one of a plurality of light transmitters and light receivers connected to a first circumference of the rotor. The segmented waveguide includes a reflective waveguide surface shaped to match a potion of existing stator surface. At least one waveguide support supports the reflective waveguide surface and is connectable to the existing stator. At least one of a light transmitter or light receiver is optically coupled to a reflective waveguide surface.
