Paper Abstract

The optical characteristics of diffractive microstructures designed for zero-order read-out are discussed. Such devices offer new optical behaviour which can be exploited for applications in the field of visual and machine readable security features. They can be fabricated by low-cost embossing and evaporation techniques.
