'Lying mirror' uses structured surfaces to conceal optical information
Mirrors normally reveal what is placed in front of them, even when their curvature distorts a reflection. Researchers at the University of California, Los Angeles (UCLA) have introduced a different optical concept: a "lying mirror" that hides information carried by an input image and transforms it into a misleading, ordinary-looking pattern at the output.
