    Abstract: A projection apparatus (10) has an illumination section with a light source (20) providing a substantially unpolarized illumination beam of multiple wavelengths. A multiple wavelength polarizer polarizes the substantially unpolarized illumination beam to provide a substantially polarized illumination beam of multiple wavelengths. A uniformizer conditions the substantially polarized illumination beam of multiple wavelengths to provide a uniformized polarized beam of multiple wavelengths. A color scrolling element provides a repeating, scrolled sequence of colors from a set of colors, thereby providing first, second, and third component wavelength illumination. A component wavelength modulating section accepts the sequence of first, second, and third component wavelength illumination from the color scrolling element and sequentially modulates the first, second, and third component wavelength illumination at a transmissive liquid crystal modulator panel (118) to provide a modulated component wavelength beam to a lens for projection toward a display surface (40).

    Abstract: A laser printer with three separate channels (12, 14, 16). Each channel (12, 14, 16) includes a gas laser (18, 20, 22) which projects a beam at a particular wavelength along the channel optical axis. A beam combiner (70) receives the light beams from the three channels and combines them to form a combined beam spot at a registration plane (108r). The combined beam spot is relayed to a polygon (102) which scans the beam onto a receiving medium (30). In order to minimize laser pointing errors and eliminate artifacts in the image, optical means (40, 42, 52, 60) are provided for adjusting the size of the beam for optimum operation and for making the combined beam spot optically conjugate with a plane (1081) in each channel at a preselected point in the channel from which the pointing errors originate.

    Abstract: A laser printer is disclosed which is adapted to be used for color imaging. The printer (10) comprises three diode lasers (97), each of which emits a light beam at a different wavelength. Each of the light beams passes along a separate channel (a-c) to a pair of dichroic plates (18, 20) which combine the three beams into a single combined beam. The combined beam is scanned by a polygon (40) onto a receiving medium (46) which is sensitive to the infrared. Two cylindrical lenses (29a, 30a, 29b, 30b, 29c, 30c) in each channel are used to focus the beam in the channel at a registration plane (32) located after the dichroic plates (18, 20). An optical relay (38) is used to transfer the combined beam from the registration plane (32) to the polygon (40) and to focus the beam in a cross-scan direction on the polygon (40). The polygon (40) is optically conjugated to the image plane in order to achieve cross-scan error correction.

    Abstract: The laser printer uses a rotating polygon (30) and a cylindrical mirror (44) disposed between the polygon and an image zone. The cylindrical mirror corrects for pyramidal errors in an output image formed on a moving photosensitive member (PM) disposed at the image zone by making the operative polygon facet and the image zone optionally conjugate in the page scan direction. To change the length (S1, S2) of the image in the line scan direction at the image zone, the optical distance between the polygon and image zone is varied by moving the cylindrical mirror. The velocity of the photosensitive member is adjusted to change the length of the output image in the page scan direction. At the new image format size, the cylindrical mirror makes the operative polygon facet optically conjugate with the image zone in the page scan direction to correct for pyramidal errors.
