摘要： An apparatus is described for optically scanning an information surface by moving said surface relative to a beam, which apparatus comprises a radiation source for supplying a beam, a collimator lens and an objective for focusing the beam to a spot in the information plane. The height of the apparatus can be reduced and/or a beam having an asymmetrical cross-section can be converted into a beam having a symmetrical cross-section by arranging a reflective diffraction grating with a suitable grating period between the collimator lens and the objective, while the angle of incidence between the normal on the grating and the chief ray of the scanning beam deviates considerably from 45.degree..

摘要： A hologram array is utilized having a plurality of adjacent holograms which are illuminated at an acute angle by laser diodes. Each laser diode output is modulated by an information source such as a computer output or the like. The outputs of the hologram array leave the hologram at an acute angle such that the focal points of the beams leaving the hologram array are focused on the object surface (a photoreceptor or the like). Closely controlled spacing of the outputs of the holograms is achieved by appropriate spacing of the holograms. In order to provide two-dimensional scanning, an appropriate combination of spherical and cylindrical lenses may be utilized together with a moving polygonal mirror to move the output beams from the hologram across the surface of the photoreceptor.

摘要： A hologon scanning system which generates an essentially bow-free scan line or lines across a surface using a planar, and preferably a holographic, grating disposed in a holding assembly which is rotated about an axis. The surface of the grating is at a constant angle of incidence with respect to a collimated beam of laser light propagating along the axis of rotation. The grating period for the wavelength of the laser beam and for the coordinate system associated with the rotating grating provides a diffraction angle from the grating which is constant with rotation angle; the diffracted beam being perpendicular to the rotation axis. An essentially bow-free, straight scan line is obtained across the receptor surface which may be a flat image plane or a cylindrical image plane having its axis along the axis of rotation of the grating. The beam scan angle across the receptor surface is equal to the angle of rotation of the grating, rather than being related to the angle of rotation by a factor approximately equal to the ratio of wavelength of the laser light to the grating period.

摘要： A plurality of laser beams are applied to a scanning medium at different positions thereon and are converted thereby to respective scanning light beams. The laser beams are modulated by color image signals representative of respective differently colored images. As the scanning medium rotates, it deflects the applied laser beams and emits them as the scanning light beams. The scanning light beams are then applied to respective photosensitive bodies to scan them, forming latent images thereon which correspond to the color image signals, respectively. The latent images are developed into respective color images which are transferred and fixed to a single recording medium thereby to form a color image thereon.

摘要： A plurality of light beams emitted by a plurality of light sources are combined together to obtain a power-multiplication effect of the beams by use of a holographic diffraction grating. The holographic diffraction grating diffracts a plurality of light beams incident thereto into such directions that the diffracted light beams advance in parallel to one another or are collimated, advance toward a point or converge, or advance as if they were emitted from a point or diverge so that the diffracted light beams can be focused to a point by use of or without a focusing optical system to multiply the power of the beams in effect. The holographic diffraction grating may be of area division type which diffracts the light beams at different portions thereof or of a multiple type which diffracts the light beams at the same portion thereof. By the former type holographic diffraction grating a single combined light beam in which the original light beams are fully merged into a single light beam is obtained, and by the latter type grating the original light beams are diffracted into collimated, converging or diverging beams.

摘要： A scanning apparatus and method for scanning a beam of light incorporate an optical system in which a rotatable wheel has a plurality of light deflecting facets on the periphery of the wheel. The incoming light beam is reflected by a routing mirror or a routing beam splitter cube onto a front face of a facet as that facet is rotated in line with the routing element. The beam is deflected as it makes its first pass through the facet, and a porro prism redirects the deflected beam back through the rotating facet so that the beam makes two passes through each facet rotating past the routing element. The scanning action is produced by the rotation of the facet in the path of both passes of the beam through the facet. The net result cancels the angular motion of the beam in one direction and adds to the angular motion in the orthogonal direction. Scanning action as produced by one facet is repeated for each facet located on the periphery of the wheel.
