FIELD: physics.
SUBSTANCE: surface of the engraved solid component is coated with a plurality of block structures having a block structure. Each block structure is a spatially limited set of modulated characteristic elements and basic characteristic elements, which are distributed on the surface of the engraved solid component. Each modulated characteristic element and each basic characteristic element have respectively a three-dimensional profile of the modulated characteristic element and a three-dimensional profile of the basic characteristic element. Each of the profiles of the modulated characteristic element is the result of applying the corresponding modulation to one of the three-dimensional profiles of the basic characteristic element in accordance with specific corresponding information. Each modulated characteristic element is additionally a symbol which is a transcription of a letter of the alphabet. Alphabet is a set of letters which are separate objects of clearly defined elementary data. Each of the basic characteristic elements is an engraved elementary three-dimensional topographic element of the surface. Each of the modulated characteristic elements is an engraved three-dimensional topographic surface element. Part of data is transcribed by means of structure of code block of modulated characteristic elements so that structure of code block forms part of block structure corresponding to part of data. Modulated characteristic elements of the first block structure are arranged in accordance with the first ordered map, wherein the first ordered map comprises at least a first final ordered set of first positions of modulated characteristic elements of the first structure of the code block on the surface, wherein the first block structure corresponds to the first part of data, and the first ordered map is further configured to accommodate modulated characteristic elements of the first block structure to form an aesthetic ensemble on the surface and displaying corresponding symbols, which correspond to modulated characteristic elements of the first structure of the code block, which are invisible to the human eye, but extracted by means of a program-controlled combination of an image sensor/processor.
EFFECT: broader functional capabilities.
