Abstract
An optical device comprises a transparent substrate having: an array of micromirrors on one surface of the substrate; and a corresponding array of microimage elements, the micromirrors presenting convex surfaces to the microimage elements whereby each convex surface causes ambient light to pass through the microimage element array from a virtual focus, the arrangement of the microimage elements and micromirrors being such that they cooperate to generate a lenticular type or a moiré magnification effect.
