Method for manufacturing in-line hologram lens

摘要

A method of producing an inline hologram lens is disclosed which includes the steps of producing a diffracted wave beam by a diffraction device, producing a spherical wave beam by an optical device, providing the diffracted wave beam perpendicularly incident on a photo-sensitive layer as a reference wave beam, simultaneously providing a spherical wave beam perpendicularly incident on the photo-sensitive layer as a subject wave beam through the diffraction device, and developing the photo-sensitive layer to produce an inline hologram lens.
