    Abstract: An erecting equal-magnification lens array plate includes a stack of a plurality lens array plates built such that pairs of corresponding lenses form a coaxial lens system, where each lens array plate is formed with a plurality of convex lenses on both surfaces of the plate. The plate receives light from a substantially straight light source facing one side of the plate, and the plate forms an erect equal-magnification image of the substantially straight light source on an image plane facing the other side of the plate. A light shielding member operative to shield light not contributing to imaging is formed in the neighborhood of a position in the intermediate plane in the erecting equal-magnification lens array plate where an inverted image of the substantially straight light source is formed. The main lens arrangement direction of the convex lenses differs from the main scanning direction of the erecting equal-magnification lens array plate.

  • Publication number: 20100142057
    Abstract: An erecting equal-magnification lens array plate includes a stack of lens array plates each formed with a plurality of convex lenses on both surfaces of the plate. The plurality of convex lenses in each lens array plate are arranged such that the main lens array direction differs from the main scanning direction. A light shielding member operative to shield light not contributing to imaging is formed in the neighborhood of a position in the intermediate plane in the erecting equal-magnification lens array plate where an inverted image is formed. The light shielding member restricts a light transmitting region of each convex lens such that lens regions outside a slit opening, which is substantially parallel with the main scanning direction, are totally prevented from transmitting light. The position of the slit opening is determined with reference to the lens coordinates of the lens surface closest to the image plane.

  • Publication number: 20100128353
    Abstract: An imaging optical system a high quality image may be implemented by determining the optimum design conditions for suppressing the generation of ghost while holding uniform and sufficient light using a simulation method. In the imaging optical system having a slit, the requirements for removing the stray light are the inclination of a lens arrangement direction, the slit width, the lens pitch, the view angle, and the height of the light-shielding wall. The slit location, the lens thickness, and the lens row width do not affect the stray light removal, but affect the brightness. In the imaging optical system having no slit, the essential requirements for removing the stray light are the height of the light-shielding wall and the lens pitch. The lens thickness and the lens row width do not affect the stray light removal, but affect the brightness.
