  • Patent number: 11400746
    Abstract: An optical device that produces flicker-like optical effects is provided. The optical device employs directionally cured image icons. Specifically, the optical device is made up of at least one arrangement of image icons formed from one or more cured pigmented materials, and at least one arrangement of optionally embedded focusing elements positioned to form one or more synthetic images of at least a portion of the arrangement(s) of image icons. Some or all of the pigmented material(s) is cured using collimated light directed through the focusing elements toward the arrangement(s) of image icons at one or more angles relative to a surface of the optical device to form directionally cured image icons. The synthetic image(s) of the directionally cured image icons is viewable at the cure angle(s) and therefore visually appears and disappears, or turns on and off, as the viewing angle of the device moves through the cure angle(s).

  • Patent number: 11002889
    Abstract: There is provided a reflective diffuser plate to achieve more uniform diffusion angle distribution properties. The reflective diffuser plate is a microlens array reflective diffuser plate including a single lens group positioned on a surface of a transparent base material. There are variations in aperture diameter and radius of curvature that respective single lenses constituting the single lens group have in the single lens group as a whole, and vertex positions of the respective single lenses are located irregularly. A luminance distribution of reflected light of light vertically incident on the single lens group is substantially uniform in a predetermined diffusion angle range. For at least light incident on the single lens group from certain directions, a relation of 0.3?A/B?1 holds where A represents a reflection luminance value in the surface normal direction, and B represents a peak reflection luminance value of a diffuse reflection component.

  • Patent number: 10974535
    Abstract: An optical device that produces flicker-like optical effects is provided. The inventive device employs directionally cured image icons. Specifically, the optical device is made up of at least one arrangement of image icons formed from one or more cured pigmented materials, and at least one arrangement of optionally embedded focusing elements positioned to form one or more synthetic images of at least a portion of the arrangement(s) of image icons. Some or all of the pigmented material(s) is cured using collimated light directed through the focusing elements toward the arrangement(s) of image icons at one or more angles relative to a surface of the optical device to form directionally cured image icons. The synthetic image(s) of the directionally cured image icons is viewable at the cure angle(s) and therefore visually appears and disappears, or turns on and off, as the viewing angle of the device moves through the cure angle(s).
