Abstract
A security device includes an array of reflective elements including at least first and second sets of reflective elements, which are regularly or irregularly interlaced along at least a first interlacing direction across a first area of the security device. A non-dispersive colour-generating structure is in the surface of first and/or second sets of reflective elements. The first set of reflective elements is configured to collectively exhibit a first image across the first area of the security device to a viewer within a first viewing zone and direct incident light convergently and/or divergently towards this zone. The second set of reflective elements is configured to collectively exhibit a second image across the first area of the security device to the viewer within a second viewing zone. The structure is modulated across the first and/or second sets of reflective elements such that the first and/or second images include multiple colours.
