Abstract:
A system for altering a functionality of an optical article from a pre-activated state to an activated state, comprising an optical article comprising an optical data layer for storing data, an external radiation source for generating an external stimulus adapted to interact with the optical article, such interaction causing a change in optical accessibility of optically stored data, a directing material, wherein said directing material is for directing the external stimulus to selective portions of the optical article, thereby altering the functionality of the optical article from a pre-activated state to an activated state; a convertible element capable of responding to the external stimulus to irreversibly alter the optical article from the pre-activated state of functionality to the activated state of functionality, wherein said convertible element comprises a color-shift dye, a magnetic material, a thermo-chromic material, a magneto-optical material, a light scattering material, a phase-change material, dye aggregates, or combinations thereof.
