IMAGE REPRODUCTION AND SECURITY MICROOPTICAL SYSTEM Russian patent published in 2011 - IPC G02B27/10 B42D15/00 

FIELD: physics.

SUBSTANCE: disclosed microoptical systems for artificial magnification include a pictogram matrix; and a matrix of pictogram focusing elements (microlens); where the matrix of pictogram focusing elements and the pictogram matrix arranged relative each other in such a way that at least one artificially magnified image having a motion effect is provided. Each of the said pictogram matrices and matrices of pictogram focusing elements have their own separate design features, for example the matrix of pictogram focusing elements can have thickness less than 50 micrometres and/or the effective diametre of the base of pictogram focusing elements can be less than 50 micrometres.

EFFECT: possibility of using disclosed engineering solutions on objects for everyday use, which are subjected to multiple mechanical effects and deformations without breaking down and deterioration of characteristics of microoptical system for artificial magnification with provision for high magnification and obtaining a clear image of protective micro-structured elements.
