    Inventors: Joseph N. Forkey, Bruce M. Radl
  • Publication number: 20220197008
    Abstract: Treated ends of optical fibers for use in an endoscope are disclosed. An end of an optical fiber, either raw cut or polished, is coated with an optical material that enables the end to be aligned without the need for conventional flush mounting techniques.
    Type: Application

  • Publication number: 20210405293
    Abstract: A system and method for treating the end of an optical fiber bundle to reduce light scattering/reflection is provided. After the end of the optical fiber bundle is formed, it has a raw end. A material is applied to the raw end to form a treated end that provides a substantially smoother surface then the raw cut end, which reduces the amount of light rays reflected from the end.

  • Patent number: 7750300
    Abstract: A thermo-optic system, which may be used for example in thermal imaging, includes an array of optical elements each having a thermally responsive optical property, the optical elements including signal elements and reference elements configured to provide (1) a common-mode response of the optical property to ambient temperature and (2) a differential-mode response of the optical property to a thermal signal appearing across the array of optical elements. The system also includes an optical readout subsystem configured to (1) illuminate the array of optical elements with optical energy at a readout wavelength corresponding to the optical property so as to generate a composite optical signal having common-mode and differential-mode signal components corresponding to the common-mode and differential-mode responses respectively of the signal and reference elements, and (2) filter the composite optical signal to generate a filtered optical signal being substantially the differential-mode image component.

  • Patent number: 4782238
    Abstract: The edges of address elements such as address labels and window apertures located on a mailpiece, are detected by utilizing illumination from first and second alternating "on" and "off" light sources which illuminate the address elements at an acute angle. In the case of label detection, the edge closest to the on illuminating source generates a high contrast image, while the edge furthest from the "on" illuminating source is shadowed. In the case of illumination of an aperture, the opposite is true. That is, the light reflected from the edge which is furthest from illuminating source is high contrast, while edge closest to the illuminating source has a lower contrast. When the images generated due to edge illumination by the left and right light sources are subtracted from each other, the edges are further enhanced due to the fact that the remaining portions of the images cancel each other out.

  • Patent number: 4469415
    Abstract: A stereo microscope has a stereo pair of photographs illuminated by a condenser lens illuminating system. A pair of primary magnifying objective lenses focus a magnified image of the stereo pair upon a pair of small diffuse screens. A pair of large aperture objective lenses focus the images on the small diffuse screens in superimposed relationship upon the plane of a large field lens that focuses respective ones of the superimposed further magnified images upon a pair of exit pupils through which an observer looks. The primary magnifying objective lens, the small diffuse screen and the exit pupils are aligned along respective left and right optical axes. The large aperture objective lenses are displaced slightly toward each other from these optical axes. The field lens is centered about an axis midway between the left and right axes.
