摘要： A method of eliminating strobing in successive scan lines of an image includes determining a nominal scan line time and an associated scan line integration time for the image sensor. A nominal illumination light source output period is determined for the illumination source. In order to ensure that the scan line integration time is equivalent to an integer number of illumination source light output periods, at least one of the nominal scan line integration time and the nominal illumination source light output period is adjusted. A clock signal, derived from the pixel clock, drives both the frequency circuitry of the lamp drive circuit and the integration time of the image sensor. The present method provides a reliable means for eliminating lamp strobing independent of the relative phasing of the lamp oscillation phase with respect to the start of each scan line integration.

摘要： A scanning apparatus includes an illuminator for illuminating a portion of a document to be scanned. The illuminator includes an array of discrete light sources and an optical element. The optical element includes a light-transmissive material and defines a focusing portion and an angular modification portion. The angular modification portion tends to reduce specular flare by modifying the angular distribution of light from the light sources which are within the acceptance angle of a lens arrangement which focuses light from the document onto a sensor.

摘要： The present invention provides a general system and method for designing arbitrary lens systems with reduced chromatic aberration without the reliance on rigorous trial and error methods and/or approximations. The system and method selects optical materials for a color corrected optical system by generating both axial color terms and lateral color terms for a predetermined lens system. From the generated color terms, a plurality of glass terms are calculated from a plurality or linear algebraic formulas generated by a multiplication of two matrices using the generated axial and lateral color terms as coefficient values of one of the matrices or other computational method. From the calculations, the particular optical materials and the predetermined lens design for a color corrected optical system are identified. This information can be used to facilitate the manufacturing of a lens system. The present invention can also take into account the use of diffractive optical elements.

摘要： A document illuminator includes a light-transmissive element having an embedded source of illumination fitted in a cavity formed therein. The light-transmissive element preferably has one or more optical notches and preferably is encased in an opaque surround to promote total internal reflection of the light rays emanating from the LED. The one or more optical notches may include a dual-V notch or an elliptical notch. The reflected light rays are collected at an aperture which in turn transmit light at high power and highly uniform illumination profile to illuminate a document.

摘要： An apparatus for recording an image on a sheet comprises a linear array of light sources and an optical element for transmitting light emitted from the light sources. The optical element comprises a light-transmissive member, having an entry surface for disposal near the light sources. The entry surface defines at least one set of prisms. The optical element can further define a DCPC (dielectric compound parabolic concentrator) in cross-section. Collection optics, such as a SELFOC® lens, receives light reflected from the sheet. Each prism of the optical element defines an angle whereby light exiting the optical element is outside the acceptance angle of the collection optics.

摘要： A raster scanner with laser for generating a scanning beam and compact, folded optical system for transmitting the beam to the object to be scanned. The optical system includes a modulator for modulating the beam in accordance with video image signals and a rotatable polygon for scanning the beam across the object to be scanned. The laser is supported at one end in a spherical bearing, permitting rotation of the laser about a point coincident with the optical axis of the scanner and at a second remote end by screw type adjustors which are used to adjustably displace the laser about the pivot point and so align the axis of the laser beam with the optical axis of the scanner. Scanner operating circuits are provided including a circuit enabling one or both of the scan detectors to serve as a light meter when aligning the laser.
