FIELD: possible use for protecting images from forgery, in advertisement, for identifying graphic applications.
SUBSTANCE: sheet material includes at least one layer of micro-lenses and a layer of material positioned near to first side of micro-lens layer, wherein by means of transmitting of radiation falling at different angles to micro-lenses separate images are formed as multiple points, wherein image is in contrast with material; and combined image provided by separate images, which for naked eye appears as floating above material or below it, or both above and below it simultaneously. Material is radiation-sensitive material. Combined image can be flat or stereoscopic.
EFFECT: possible production of sheet material with image which can not be used for copying.
