A Novel Optical Rotating-to-Fixed Signal Transmission Technology Providing Multichannel, High Data Rate,

Motivated by the recent Air Force need for an "Optical Slip-Ring Connector (OSRC)." Physical Optics Corporation (POC) proposes to investigate a novel, optical, rotating-to-fixed information transmission (ORFIT) technology by using POC's proprietary non-imaging-optics (NIO), wavelength division multiplexing (WDM), and fiber optics technologies. POC's ORFIT solution should solve major problems associated with the currently used copper slip-ring, cablewrap, and waveguide rotary-joint approaches, as well as provide a universal, expandable rotating-to-fixed information transmission system. POC's ORFIT system consists of a pair of small photonic heads (PHs). Each PH is , in turn, composed only of two compact optic and photonic components: (1) a light receiving and transmitting NIO or GRIN rod component, and (2) an optical fiber WDM and transceiver component. POC's ORFIT system is expected to provide the following features: small, light, and compact; reliable, safe, with long life; ultichannel, high data rate, wtih bi-directional transmission; and, commercialization potential.
