More Information
Summary:A method for replicating a holographic optical element and a holographic optical element replicated thereby are provided. The holographic optical element is larger than a master. The master has a holographic grating pattern generated on the master by interference of the reflected, diffracted or transmitted beam generated by irradiating the master having a specific diffraction grating pattern formed thereon with a laser beam.
