Abrégé
The invention discloses a diffractive device and a method of creating the same displaying a three-dimensional preferably achromatic image, especially imitating a real or an imaginary relief scene, a flat microrelief or otherwise modulated structure (10) of a diffractive type is created, the structure (10) comprising system of diffraction zones (5) which are arranged so that in places of diffractive structure (10) corresponding to places of the relief scene (11) the diffraction zones (5) have such periodicity and orientation (a, b) that cause deflection of incident light (9) in the same direction as the relief scene (11) deflects an incident light, thus achieving a visible thee-dimensional and largely achromatic sensation of image, corresponding to the relief scene (11), when observing the diffractive structure (10) regardless of conditions of lighting. A diffractive element comprises diffractive structure (10) with a system of diffraction zones (5) arranged so that in places of diffractive structure (10) corresponding to places of the relief scene (11) they have such periodicity and orientation (a, b) that cause deflection of incident light (9) in the same direction as the relief scene (11) deflects an incident light, for achieving a visible thee-dimensional and largely achromatic sensation of image corresponding to the relief scene (11) when observing the diffractive structure (10) regardless of conditions of lighting. In another aspect of the invention there is revealed the use and combination with an additional micro-relief with its fine structure, together with variability of reflections and transmissions of specific elementary areas which enables a visual imitation of various materials, structures and patterns.
