RELIEF REFLECTING OPTICAL STRUCTURES

摘要

Optical structure includes light guide material that has surface relief pattern applied to it, like hologram. Relief layer of reflecting material is applied over sections of surface relief pattern in such way as to form alphabet-digital signs, bar-codes or drawn or graphical patterns. Optically active coating is applied over relief layer of reflecting material and open sections of surface relief pattern for formation of needed optical effects on open sections of surface relief pattern. In some variants of implementation optically active coating is thin film with effect of shift of color or it has scraps with effect of color shift. Material of optically active coating can have refraction coefficient that is agreed with coefficient for light-conductive material for optical deletion of effect of surface relief pattern on sections of surface relief pattern not closed with reflecting material.
