    摘要： A system for concurrently imaging the first and second sides of different sequential duplex documents in alternating image lines alternating between the first and second imaging stations. This system is shown in a system for imaging both of the first and second opposing sides of duplex documents with higher productivity, with a generally "V" shaped low profile document sheet feeding path with first and second arms merging at a base position having a document reversing system, for sequentially feeding documents from an input tray through the first arm to the base position, and then back through the second arm to an output tray. A first imaging station is in the first arm for imaging the first sides of the documents, and a second imaging station is in the second arm for imaging the second sides. Both imaging stations have a simple, partially shared fixed elements optical system mounted entirely inside the document path, which can share a single electro-optical digital imager. The duplex documents are not inverted, yet are returned to the output tray in the same orientation as the stack in the overlying input tray. Compatible simplex document copying can also be provided.

    摘要： A short focal length lens array has a plurality of lenslets formed within the body of a photosensitive glass. The lenslets have areas which are oriented such that they tilt away from each other from the center out to the array edges. The lens array acts as a reduction or enlargement lens when reproducing objects at an object plane onto an image plane. A one or two row embodiment is disclosed suitable for incremental scanning of a document at image planes. A further full frame lens array is disclosed for providing full frame exposure of a document at various selected magnifications.

    摘要： A compact, two-dimensional full-frame document illumination and imaging device is formed by combining a short focal length imaging area array, such as a gradient index fiber lens area array, with a light source formed in the fiber interstitial areas of the array. The light source is addressed to provide a uniform illumination level at a document platen interface. The full document image is reflected back to the array and projected onto a photosensitive image plane.

    摘要： A two-dimensional full-frame illumination assembly is formed, in a preferred embodiment, by coupling light into the edges of a document platen which has been modified by applying a white segment pattern to the bottom platen surface. The coupled light is totally internally reflected within the platen body except for the area covered by the segment pattern. Light encountering the segments is reflected upward towards the document support surface to provide the required document illumination. The light reflected by the document passes back through the screen segment pattern and is projected by a conventional lens or a full-frame, two-dimensional, short focal length lens array onto a photosensitive surface such as a photoreceptor belt.

    摘要： An illumination system for a document copying machine including an optical cavity having interior walls coated with a white, diffusely reflecting material. One end of the cavity contains a platen for positioning document to be copied while the opposing end contains a lens for forming an image of the document on a light sensitive image plane. Illumination from a single flash illumination source located within the cavity, undergoes multiple reflections from the walls resulting in a uniform diffuse illumination of the document.

    摘要： Pre-polygon optics are provided which consist of a compact design such that the number of pre-polygon elements in the pre-polygon optics is reduced while achieving desired light beam characteristic. The pre-polygon optics may consist of a hybrid toroidal diffractive optical element, refractive cross-cylindrical optical elements, refractive spherical and cylindrical optical elements, a refractive sagittal cylindrical optical element or a refractive tangential cylindrical optical element. Accordingly, advantages such as lower cost and ease of alignment are achieved.
