Abstract
Moiré-type magnification systems are disclosed. The moiré magnification systems can comprise a surface and a periodic array of image relief microstructures having a periodic surface curvature disposed on or within the surface. The image relief microstructures can have a first image repeat period along a first image reference axis within the array, and the periodic surface curvature can have a first curvature repeat period along a first curvature reference axis within the array. Transmission of light through the array, reflection of light from the array, or a combination thereof forms a magnified moiré image.

A moiré magnification system comprising
- (a) a surface;
- and
- (b) a periodic array of image relief microstructures having a periodic surface curvature disposed on or within the surface,
- wherein the image relief microstructures have a first image repeat period along a first image reference axis within the array,
- wherein the periodic surface curvature has a first curvature repeat period along a first curvature reference axis within the array, and
- wherein transmission of light through the array, reflection of light from the array, or a combinations thereof forms a magnified moiré image.
