Abstract: A radiographic imaging system and digital detector detect extraneous signals during DR detector image readout and compensate or remove extraneous signal artifacts from radiographic images. Novel capture and post processing procedures prevent undesirable noise artifacts from appearing in final radiographic images.

Abstract: An apparatus for transporting a sheet recording medium (12) has an entrance drive roller (16) paired with a corresponding entrance pressure roller (18) to form an entrance nip (14) for transporting the sheet recording medium (12) into a scanning section (20) between the entrance nip (14) and an exit nip (24). The exit nip (24) is formed by an exit drive roller (26) with a corresponding exit pressure roller (28) for transporting the recording medium (12) out from the scanning section (20). At each end of the entrance pressure roller (18), an entrance pressure roller actuation arm (120) actuates the entrance pressure roller (18) to exert variable force against the entrance drive roller (16). At each end of the exit pressure roller (28), an exit pressure roller actuation arm (130) actuates the exit pressure roller (28) to exert variable force against the exit drive roller (26).

Abstract: A method of detecting the relative skew between a reference beam and transparent lenticular material of the type having a repeating pattern of cylindrical lenses, comprising the steps of: forming a beam of light; focusing the beam of light into a line with a width smaller than the pitch of the cylindrical lenses onto the lenticular material; moving the lenticular material relative to the beam in a direction such that the beam crosses the longitudinal axes of the cylindrical lenses to modulate the angle of reflection or refraction of the beam of light; and sensing the position of the line of modulated beam of light along a line parallel to the longitudinal axes of the cylindrical lenses to determine the skew or relative angular location of lenticular material to the focused line.

Abstract: A lenticular image product is formed from a lenticular material having an array of cylindrical lenses and a photographic emulsion coated thereon, by scanning the lenticular material with an intensity modulated first beam of light in a direction parallel to the long axes of the cylindrical lenses to form a latent lenticular image in the photographic emulsion. A second beam of light having a wavelength outside of the range of sensitivity of the photographic emulsion is focused into two distinct spots or a line both with a width smaller than the pitch of the cylindrical lenses onto the lenticular material. The lenticular material is moved through the beam in a direction perpendicular to the axes of the cylindrical lenses to provide a page scan motion of the lenticular material and to modulate the angle of reflection or refraction of the second beam of light.

Abstract: A position sensor having an opto sensor and an optical density gradient wedge photo interrupter in which the gradient wedge comprises a half tone dot pattern preferably photographically reproduced in a photosensitive medium. In a preferred embodiment, the half tone dots are formed with microdots that are cumulated to increase the density of the half tone dots. In regions of density variations where the half tone dots change shape between round and square (in both solid fill and open fill dots), a random fill pattern is employed to enhance the linearity of the sensor output signal. The beam width of the opto sensor is uncollimated and focused to cover at least three pixel widths of the half tone dot pattern where each pixel is formed of at least four half tone dot areas.
