Abstract: The present invention provides for an imaging device such as a scanner or printer. The imaging device includes a unique media gate arrangement in which each of the media gates is positioned along the same optical axis. This provides for a gate arrangement in which media of a first format will be conveyed across one of the gates and media of a second format will be conveyed across a second one of the gates. With the arrangement of the present invention it is not necessary to change a media gate based on the format of the film or media used, since the media gates based are positioned along the same optical axis and are positioned such that the light beam passes through both gates.

Abstract: A digital projector that has closed loop three color alignment comprising a light source where an optical engine (50) splits a beam of light from the light source into first, second, and third wavelength bands. A first, second, and third spatial light modulator (11, 12, 16) imparts image data and first, second, and third fiducial data respectively to the first, second, and third wavelength bands. The first, second, and third wavelength bands are directed to the first, second, and third spatial light modulator (11, 12, 16), respectively. A combiner combines the modulated first, second, and third wavelength bands. A diverter (19) diverts a portion of the combined modulated wavelength bands to at least one sensor. The sensor (21) then senses a relative position of the fiducials and sends the position information to a microprocessor. The microprocessor then determines an error based on the relative position of the fiducials.

Abstract: An object bearing a two-dimensional visible image on an image field of a non-planar and curved object surface in at least one dimension also bears an encodement of encoded information recorded in a symbology of a material that is visible or invisible to the eye and over a substantial portion of the image field. The encodement includes curved encodement portions due to the curvature of the non-planar image field. The symbology of the encodement is adapted to be imaged as a planar symbology image by a planar imager that is disposed in use generally normal to and at a predetermined distance from a central point of the two-dimensional visible image. The recorded symbology is adjusted from point to point in the image field during recording of the encodement by an encodement recording system to compensate for distortion of the symbology introduced by imaging the curved symbology portions as the planar symbology image.
