Abstract
A micro-optic device, including: a substrate; a plurality of image elements; and a plurality of focusing elements, each focusing element focuses light towards, or causes light to be diverged from or constructively interfere at a real or imaginary focal point, the focusing elements causing the image elements to be sampled so as to project imagery which is observable to a user from at least a first viewing angle, wherein a first focusing structure including at least a first group of the focusing elements and a first imagery structure including at least a first group of the image elements are integrated into a first unitary structure on a first side of the substrate.
Claims21
A micro-optic device, including:
- a substrate having a first and a second side, opposite the first side;
- a plurality of image elements;
- a plurality of focusing elements, the focusing elements each having a convex surface, each one of the focusing element focusing light towards, or causing light to be diverged from or constructively interfere at a real or imaginary focal point;
- and
- a first focusing structure including at least a first group of the focusing elements and a first imagery structure including at least a first group of the image elements integrated into a first unitary structure on the first side of the substrate;
- wherein the topography of the image elements is raised, protruding or extending above the convex surfaces of adjacent focusing elements and the focusing elements cause, at least, some of the image elements to be sampled so as to project imagery which is observable to a user from, at least, a first viewing angle, and
- wherein the image elements each have a planar upper surface.
