Method and apparatus for applying diffractive elements onto surfaces

摘要

The method involves transferring holographic information to a light-sensitive recording layer applied to the surface of the object. In a repeated manufacturing process, diffractive elements to be sequentially formed are varied by changing the holographic information transferred and/or changing the arrangement of the light-sensitive layer on the surface. Independent claims are included for an object with a diffractive element, and for a method of manufacturing an object.
