摘要: A micro-optic security device (100) includes a planar array of micro-optic focusing elements (105) and a first arrangement of image icons (120), wherein each image icon (121) of the first arrangement of image icons includes a region of light-cured material. Further, the first arrangement of image icons is visible (320) through the planar array of micro-optic focusing elements across a first predetermined range of viewing angles relative to the micro-optic security device, and the first arrangement of image icons is not visible (360) through the planar array of micro-optic focusing elements across a second predetermined range of viewing angles relative to the micro-optic security device.
