    Abstract: A lens system for a folding reflex camera is provided. The system includes: (a) a first group on the object side of the system's stop which (i) has a positive dioptric power, (ii) includes an aspheric surface, and (iii) has a concave surface adjacent to the stop; and (b) a second group on the image side of the stop consisting of either a single positive component or the combination of a single positive component and one or more focusing elements. The system includes at least two elements made of materials differing in dispersive powers where at least one of the elements is of plastic. The system can comprise just two plastic elements and even with such a simple configuration achieves excellent optical performance including a relatively flat field, relatively low distortion, and at least partial correction for lateral chromatic aberration.

    Abstract: An imaging medium comprises means for providing a light-reflecting layer, an image-receiving layer for receiving image-forming components, a transparent layer superposed over the image-receiving layer such that an image in the image-receiving layer can be viewed through the transparent layer against the light-reflecting layer, and an image enhancement layer disposed between the image-receiving layer and the transparent layer, the image enhancement layer having a refractive index less than that of the transparent layer and the image-receiving layer and not greater than about 1.43. The image enhancement layer decreases internal reflections within the medium and thereby improves the quality of the image seen. The imaging medium can be used as the imaging element of a diffusion transfer process film unit.

    Abstract: Color film which has relatively high photographic sensitivity, improved spatial sensitivity and reduced problems with aliasing between film stripe structure and scene content and from which full color photographic information can be extracted. An embodiment of the color film includes a black and white photographic film emulsion which is coated upon a substrate, which emulsion is covered with a repetitive pattern of a triad of: (a) color stripes such as yellow, green and cyan stripes wherein at least one of the colors is a nonprimary color; (b) color stripes of unsaturated hues such as, for example, pastel yellow, pastel green and pastel cyan stripes wherein at least one of the colors is a nonprimary unsaturated hue; or (c) color stripes of unsaturated hues of any color. Full color prints or enlargements are made by a hybrid process which includes electronic scanning to extract color information and an optical or an electronic method to extract detail information.

    Abstract: The structure of a miniature component for use in connecting optical fibers along with methods for fabricating the component. A small scale tube having precision surfaces inside and out has formed directly in it a converging, preferably plastic, lens capable of imaging a fiber end properly located into assimilarly situated fiber in another like facing component. The outside precision surfaces of the tube serve as references for precision alignment of the component while its inside precision surfaces aid in formation of the lens.

    Abstract: Phase array apparatus for use with a lens system to provide a substantially smooth, uniform image of a laser array comprised of a multiplicity of lasers wherein the phase of the radiation emitted by the lasers alternates by an amount which is substantially equal to 180.degree.. The phase array includes: (1) phase means, disposed substantially at a far-field image of the laser array formed by the lens system, which far-field image comprises two prominent lobes, for changing the phase of the radiation in the two prominent lobes by 90.degree. with respect to the phase of the remaining radiation in the far-field image in order to convert the near-field image of the laser array into a finite-length sine pattern and (2) means, such as a wedge prism or a split lens, disposed preferably near a far-field image but not at a near-field image, for angularly shifting one half of the phase shifted far-field image with respect to the other to form a pair of near-field images which are spatially shifted with respect to each other by one-half cycle of the sine wave, whereby a substantially smooth, uniform image of the laser array is formed.

    Abstract: A CCD pixel pattern for receiving an image to be recorded by a rotary head printer as a series of record track scans each having a predetermined curve geometry. The pixels are arranged in rows having a curvature proportional to the record track scan geometry so that the physical location of incident image light seen by each pixel will correspond directly to the physical location of the printed image increment originating with each pixel, respectively.

    Abstract: A system utilizing aspects of both photography and electronic imaging is provided for recording and reproducing an image of scene in color. A camera component of the system photographically records the image on monochromatic film to provide a high resolution photograph from which electronic luminance signals are derived, and also utilizes an image sensor for providing lower resolution chrominance signals which are recorded on a medium, such as a magnetic stripe, that may be formed on the film unit. The photograph and chrominance signal recording are transferred to a reproduction component of the system which derives the luminance information signals from the photograph and combines it with the chrominance signals to provide three primary color signals which are utilized to drive a hard copy printer or an electronic image display device.
