摘要
Provided is a method of manufacturing a full-color holographic optical element in a full-color holographic optical element manufacturing apparatus including a lens and a holographic recording medium located farther away than a focal length of the lens, the method including: allowing a signal beam including a mixture of laser beams having wavelengths of R (Red), G (Green), and B (Blue) to be incident on the lens; and recording a hologram in such a manner that a reference beam including a mixture of laser beams having wavelengths of R, G, and B is allowed to be incident on the holographic recording medium, wherein the holographic recording medium is configured with a single medium. Accordingly, a hologram is recorded in a single medium using a photopolymer instead of a full-hologram holographic optical element in the related art, so that it is possible to prevent distortion caused by reflected light, to obtain a constant yield, and to improve diffraction efficiency.
