Circular scanning system for an integrated camera and panoramic catadioptric display

摘要

A circular scanning system for an integrated camera and catadioptric display has a photon camera tube with a scanning beam, a pixel clock generator for generating a pixel clock signal, a clock dividing arrangement for generating beam rotation signals, and a ramp signal generator for generating a beam radius transversing ramp signal being synchronous with the beam rotation signals. It also has an arrangement for generating a beam angle step signal for moving said beam in alternating interlaced frames and can accommodate a plurality of viewing stations, each directed to viewing a selected section of the image.
