Document Type and Number:
WIPO Patent Application WO/2022/045758
Kind Code:
A1
Abstract:
[Abstract] The present invention relates to a method for replicating a holographic optical element and to a holographic optical element replicated thereby, wherein the method replicates a holographic optical element which has a holographic grating pattern implemented, on a mask having a specific diffractive grating pattern formed thereon, by means of interference of reflected, diffracted, or transmitted light generated by irradiating laser light to the master, and which has a larger area than the master.
