Abstract
An optical device projecting one or more synthetically magnified images that has been laser marked with one or more static two dimensional (2D) images is provided. The static 2D image(s) laser marked on or within this device and the synthetically magnified image(s) projected by this device help determine the authenticity of a document (e.g., passport data page) or product that employs it. Several embodiments of the inventive device also offer increased resistance to tampering or alteration and wear.
