Latest Patents

Holland holds a patent for a "Method of preparing a multicolored holographic image." This patent describes a technique for preparing a silver halide sensitized hologram with interference fringes that are generally parallel to the substrate. The method involves an imagewise photographic exposure using actinic light, followed by a holographic exposure using laser light. The unique aspect of this method is that the reference beam enters the holographic material from the opposite side of the object beam. The exposures can be either sequential or simultaneous. After developing the holographic material with a silver halide developing agent and bleaching out the developed silver, the processed hologram exhibits a multicolored appearance. This effect is achieved through differential shrinkage of the emulsion, which occurs due to varying exposure levels.
