Galvonometric scanning and imaging with multiple beams reflected from an oscillator |
摘要 |
Multiple light beams are reflected by a resonant oscillator through an optical system onto light sensitive drums of a printing system. Information is encoded onto the beams, and an image is printed based on the encoded information. Preferably four beams and four drums are used to print four colors. The oscillator includes an oscillating plate mounted on the torsion springs for resonant oscillation. A magnet is mounted on the oscillating plate and an oscillating magnetic field oscillates the magnet and the plate. Sensors detect the position of at least one of light beam to synchronize the operation and speed of the encoder, drums and oscillator. The oscillator may include multiple reflective surfaces on one or more sides of an oscillating plate, and one or more beams may be reflected from each surface.
