Title:
METHOD OF DUPLICATING A HOLOGRAM AND HOLOGRAM OPTICAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2022/262661
Kind Code:
A1
Abstract:
A method for duplicating a hologram and a hologram optical element comprises: preparing a master with a master hologram; preparing a sample with coated photoalignment material layer above the master; and irradiating a recording light through the sample to the master, so that at least one portion of the recording light is reflected by the master as an object light carrying the master hologram information, and so that the object light and the recording light are interfered at the photoalignment material layer to produce a duplicated hologram in the photoalignment material layer.
