FIELD: physics, optics.
SUBSTANCE: diffraction structure comprises a plurality of channels assembled to generate a first diffraction optical effect. Each channel is formed from a plurality of scattering and/or diffraction channel elements, each aligned to provide a second scattering and/or diffraction optical effect to form a micro- or macro-distinguishable graphic feature. The method of creating a diffraction surface relief structure involves forming a plurality of scattering and/or diffraction channel elements with alignment, which serves to form a plurality of channels that are assembled to generate a first diffraction optical effect. Each of the plurality of channel elements is assembled to provide a second scattering and/or diffraction optical effect to form a micro- or macro-distinguishable graphic feature.
EFFECT: creating a unique, highly secure feature which is difficult to imitate and can be combined with any optically variable features.
