Abstract (en)
[origin: US6243202B1] A structural arrangement having optical diffraction qualities for use as a security element in a value bearing document, such structural arrangement having a plurality of surface regions having at least two subregions having identical relief structures which provide for an optical diffraction effect, the relief structures of adjacent subregions being displaced relative to each other by a fraction of the grating period.
