    Abstract: Photographic indicator apparatus is provided for use in a folding type camera with a collapsible viewing device to provide a signal which is visible through an eyelens of the camera viewing device and which indicates that available scene light is below a threshold value which requires the use of an artificial light source to provide supplemental illumination of the scene or which will cause blurred pictures if the camera is hand held and no artificial light source is used. The low available scene light signal originates from an LED which is made visible through the eyelens by a specially configured prismatic optical element that defines a deviated optical path between the eyelens and the LED.

    Abstract: A compact and inexpensive method and apparatus for illuminating and acquiring a digital image of a biometric feature such as a fingerprint, palm print, footprint, or some subset or multiple of such features. A source of illumination (11) is introduced into an exposed edge of a transparent optical window (13) that is essentially smooth and generally flat with spaced apart surfaces. The illumination propagates between the surfaces of a flat or slightly curved transparent window (13) via total internal reflection (15) to obliquely illuminate a biometric feature (12) when in contact with the window (13). A digital camera (17) views the obliquely illuminated biometric feature (12) to record an image of it which can then be compared with registered images for matching and control purposes.

    Abstract: An optical component mounting device and method is disclosed where the optical components are disposed within a thin-walled tube and the tube is configured to produce an interference fit within the cylindrical opening of a mounting sleeve. The optical components are secured to the tube such that their optical axes coincide with the tube longitudinal axis. Mating of the optical mounting assembly to external reference surfaces precisely locates and aligns the optical axes with respect to an external reference axis. The optical mounting assembly provides at least two degrees of freedom to the optical components for facilitating alignment.

    Abstract: A lens composed of a single material and having at least one refractive surface on one face and a kinoform on the other face. The purely refractive between the surfaces varies dimensionally and in refractive index in response to temperature changes and thereby changes a characteristic, such as back focal length, of the lens while the kinoform varies differently in response to the same temperature changes. The kinoform power is sufficient to vary the temperature induced characteristic changes of the lens in an opposing sense at a given wavelength and in an amount sufficient to athermalize the optical device. In one embodiment the kinoform power compensates for the combined temperature-induced effects upon the refractive portion and any mount that supports the lens.

    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: Apparatus for improving the quality of an electronic image generated by a charge coupled device (CCD) array that senses scene images through a colored optical filter. The apparatus includes a prism or prismatic filter movable into and out of the path of image-containing light rays impinging on the color filter overlying the CCD array that alternately shifts the scene image between color filters of the CCD array that absorb particular scene image colors and those that transmit these colors to their associated CCDs while in the case of the prismatic filter absorbing the dominant scene color generated by the colored optical filter. Scene image signals generated by a CCD array in this manner are processed such that their spatial relationship with respect to the sensed scene image is precisely monitored and electronically counter-shifted for subsequent scene image reconstruction. By shifting the scene image between individual CCDs having different color optical filters, most of the CCDs in the CCD array can generate image signals for two different scene colors or scene color combinations and thereby improve the image resolving capabilities and/or the color balance of electronic images generated by the CCD array.

    Abstract: An imaging component of unitary construction, molded of a transparent optical plastic, and adapted for use with a companion, preferably similar, component to optically couple optical fibers with one another. The component includes a lens surface arranged about an optical axis therethrough, a reference surface for facilitating mounting and positioning the component, and structure for facilitating receiving and positioning the end of an optical fiber at a fixed distance along the optical axis and behind the focus of the lens surface. The optical structure of the component is such that, when used with another axially spaced by a fixed distance and operating at finite conjugates as a pair, the optical fiber end in each is exactly imaged onto or within the entrance pupil of the other. This permits the axial separation between the two components to be substantially greater than the focal length of their lens surfaces so that, among other things, other components such beam-splitters can be introduced between the pair to perform multiplexing functions.
