  • Patent number: 5952148
    Abstract: The invention discloses that a photograph with a 3-dimensional image results when the non-angular reflector (of mercury) used in the Lippmann process of color photography is replaced by an angular reflector; the preferred form of the angular reflector is a retro-reflector.A photographic system is described which produces photographs with 3-dimensional images. The photo-sensitive element records the interference patterns of light waves, and the system is an improvement over the Lippmann process of color photography which produces photographs with 2-dimensional images. A photographic system is also described that produces a photograph with a 3-dimensional image from 2-dimensional cross sections of a subject; the system is useful in medical imaging. During exposure, motion of more than one wavelength of light is permissible between the subject and lens or the lens and the photo-sensitive element.These improvements result from the use of a particular type of angular reflector which is a retro-reflecting sheet.

A first method forms between the substrate and resist film an anti-reflective film whose photoabsorbance of the exposure light is greater on the substrate surface side than on the resist surface side. A second method forms between the substrate and resist film a two-layer anti-reflective film made up of an upper-layer film which is an interference film for the exposure light and a lower-layer film which has higher exposure light absorbance than the upper-layer film and functions as a light shielding film.

  • Patent number: 5328811
    Abstract: A method of printing an image on a substrate by applying to the substrate a film which is chemically activated by heat, and scanning the film by a beam of radiation according to the image to be printed, to chemically activate the film by heat and thereby to produce a pattern in the film according to the image scanned. The film includes a reagent capable of undergoing a redox reaction when heated in the presence of another reagent present with the film when scanned by the beam, to produce the redox reaction between the two reagents.

  • Patent number: 5318885
    Abstract: A photographic element according to the invention includes a reflective support, one or more photosensitive silver halide emulsion layers, and a colored antihalation layer interposed between the support and the photosensitive layers. The antihalation layer comprises thin grains of silver in the form of-platelets having a thickness of up to about 20 nm. The platelets are distributed in a suitable matrix or colloidal medium such as gelatin. The thinness of the platelets allows the antihalation layer to be formed effectively at lower silver levels.
