Abstract
Dibujo de superficie de elementos de superficie (1 a 7) colocados en forma de mosaico, que presentan estructuras en relieve microscópicas, de los que una pluralidad de elementos de superficie divididos (2 a 6) está subdividida al menos en primeras y segundas superficies parciales (8; 9) y que contienen rejillas de difracción asimétricas (12; 13) con efecto de difracción óptica, divididas en elementos de superficie (2 a 6), en el que en los elementos de superficie divididos, subdivididos (2 a 6) están separadas primeras superficies parciales adyacentes (8) por segundas superficies parciales (9) y los vectores de rejilla de las rejillas de difracción asimétricas (12; 13) de las primeras superficies parciales (8) y de las segundas superficies parciales (9) se separan en el acimut, en el que las rejillas de difracción asimétricas (12) de las primeras superficies parciales (8) de todos los elementos de superficie divididos (2 a 6) poseen el mismo primer valor del acimut y las rejillas de difracción asimétricas (13) de las segundas superficies parciales (9) de todos los elementos de superficie divididos (2 a 6) poseen el mismo segundo valor del acimut, caracterizado, porque la relación de la suma de todas las primeras superficies parciales (8) del enésimo elemento de superficie dividido a la superficie total del enésimo elemento de superficie dividido forma un valor fraccional de superficie AN propio del enésimo elemento de superficie dividido, y porque a lo largo de un eje marcado predeterminado (14) todos los elementos de superficie divididos (2 a 6) están dispuestos conforme a su valor fraccional de superficie AN entre los elementos de superficie divididos con el valor fraccional de superficie AN=0 y AN=1 en el mosaico de todos los elementos (1 a 7).
