Abstract: A gradient index lens array is provided with reduction and enlargement capabilities. Gradient index fibers are arranged in single row or double row (bundled) configuration with fibers increasingly departing from the perpendicular condition at the center of the array relative to object and image planes in a characteristic fan-like manner. Fiber lengths are adjusted to compensate for changes in total conjugate which occur because of the progressive tilting of the axes of the individual fiber lenses. This is achieved, in one embodiment, by grinding the faces of a lens array into a convex configuration.

Abstract: A multiple function image processing system having both light-lens and flying spot beam for producing latent electrostatic images of originals on a photoconductive surface. The images are developed and transferred to a copy substrate material. A flying spot image reading beam enables the developed images to be read. Where multiple copies are desired, the light/lens provides the first image with later copies provided by the flying spot beams which scan each developed image and, using image signals produced by said scanning, write the next successive image until the desired number of copies are produced. Where a relatively large number of copies are desired, the image signals produced by scanning the developed image are stored in memory, which is thereafter used as the source of image signals for subsequent copies.

Abstract: Flow systems for photometric analysis of particles, such as biological cells, particularly for obtaining multidmensional slit-scan type contours, as well as other images. In one broad approach, fluorochrome-stained cells in suspension flow through a focused slit of laser excitation light defining a planar excitation region in the X-Y plane. As each fluorochrome-stained cell flows through the excitation region, fluorescence emissions are generated at the intersection of the excitation region and the cell. To generate a slit-scan type contour along the Z axis, fluorescence emissions are monitored as the cell flows through the excitation region and a plurality of substantially planar parallel cross-sections of the cell along the Z axis are excited to fluorescence. To generate slit-scan type contrours along the cellular X and Y axes, various optical system embodiments define various combinations of cellular linear portions within the Z axis cross-section.
