Abstract

A homogeneous randomly distributed microlens array (MLA) and a corresponding micropattern array are integrated onto a layer of polyester film aiming to give rise to a special dynamic Glass pattern. Integrating an MLA and a micropattern array, and applying a small geometrical transformation, it is possible to show the parallactic or the orthoparallactic motion effect when varying the viewing angle. Both numerical simulation and experimental results are present in this Letter. Such devices can find potential applications in precision optical alignment, image registration, and document security and authentication.
