Rotation-Selective Moiré Magnification of Structural Color Pattern Arrays.

ACS Nano, 2019
When a microlens array is aligned and overlaid on an array of patterns with similar periodicity, a highly magnified image of the patterns is observed. This effect, known as moiré magnification, is used to reveal micropatterns that are unresolvable by the
