  • Patent number: 4882262
    Abstract: An apparatus and method for creating an aperture between the lenslets of a lenslet array, which lenslet array has been produced by a process that leaves at least partially opaque barriers between the lenslets, comprising utilizing a photoresist over the entire surface of the lenslets and the spaces therebetween and shining ultraviolet light from the back of the array so that light exposes the photoresist in the lenslet portions and not in the areas therebetween.

  • Patent number: 4863819
    Abstract: A data card comprising a self-supporting, wallet size plastic card base upon which is disposed a film substrate layer, a highly reflective layer and an optical storage layer which is a selected photosensitive layer which has been exposed at an actinic wavelength and developed to be substantially opaque over a portion of its extent, except for an imagewise exposure pattern of clear and partially clear data marks revealing to varying extends reflectivity in the underlying reflective layer. Data spots may have one of four different reflectivities thereby representing a quadrinary digit 0, 1, 2 or 3 replacing two binary digits. The reflective layer is matched to the selected optical storage layer so that the reflective layer is highly reflective at a read beam wavelength in the red or near infrared and less reflective at actinic wavelengths either in the blue/green range or in the ultraviolet.

  • Patent number: 4798782
    Abstract: This invention relates to poly(acetylene) films having localized zones of a material other than poly(acetylene) with modified optical and electrical properties. The films are formed by selectively irradiating discrete areas of a film of a precursor polymer followed by heating of the irradiated precursor polymer to transform the non-irradiated areas into poly(acetylene). The resultant product has localized zones of modified electrical and optical properties which are useful in the semiconductor industries and in optical devices.

  • Patent number: 4497892
    Abstract: A method and apparatus for generating a negative or positive image from a single photographic medium. A source of radiant energy is projected onto a sheet of dielectric material heating the material to a polarizing temperature. A pair of electrical conductors are moved in a first direction along the surface of the heated dielectric material polarizing the material in the first direction. A photographic mask is then positioned over the polarized material and the radiant energy and the electrical field is again applied through the mask in a second direction to polarize certain portions of the material in the second direction. Projecting polarized light through the dielectric material and rotating the material during the projection produces a negative or positive image on the screen.

This layer is reflective, as by incorporation of a white pigment, so that the image is seen through the transparent film against the background of this layer rather than the main support. The reflective layer may contain other chemicals relevant to processing.
