MICRO-OPTICAL PROTECTIVE DEVICE WITH LAYERS OF PHASE-SYNCHRONIZED IMAGES Russian patent published in 2024 - IPC G02B27/12 B41M3/14 

FIELD: physics.

SUBSTANCE: invention relates to microoptical protective devices. Protective device includes a planar array of microlenses which are configured to focus radiation along a plurality of focal paths associated with the viewing angle. Microoptic protective device further includes a stack of layers of pictograms arranged along a plurality of focal paths. Stack of layers of pictograms includes a first layer of pictograms with volumes of cured material of a first colour and volumes of substantially transparent material in locations along focal trajectories of the first range of viewing angles. Stack of layers of pictograms also includes a second layer of pictograms with volumes of substantially transparent cured material at locations along focal paths of the first range of viewing angles; and volumes of cured material of second colour at locations along focal trajectories of second range of viewing angles.

EFFECT: invention provides higher quality of visual effects.
