Rotating optical communication link for use in computer tomography has waveguide rotating with drum to transfer data to stationary monitoring equipment

摘要

An optical emitter (150) injects scanning data into an optical waveguide (120). In response to an electric field, light or magnetic energy or heat generated in an induced radiation wave chamber (110), a total reflection break is induced in the waveguide section embraced by the chamber. This causes reflection of the data signal from the waveguide to the chamber with no reflection outside the chamber, and an optical detection device (180) picks up the interrupted data
