FIELD: physics.
SUBSTANCE: described is an artificial microoptic system and a protective device, which include a planar image formed from a matrix or a pattern of pictograms and a matrix of focusing elements; the system forms at least two different artificial images, owing to which one artificial image serves to regulate or control the degree of visibility of the other artificial image. In a typical form, the matrix of pictograms forms a planar artificial image, while interaction of the matrix of focusing elements with the matrix of pictograms forms a separate artificial enlarged image which serves to control the field of view of the planar image, thus serving to regulate or control the degree of visibility of the planar image. Therefore, the planar image visually emerges and disappears, or is turned on and off, depending on the viewing angle of the system.
EFFECT: improved system.
