HOLOGRAPHIC OPTICAL ELEMENT AND PRODUCTION METHOD THEREFOR

摘要

The present invention provides a means for improving diffraction efficiency and suppressing ghosting with respect to a holographic optical element having a volume hologram recording layer.　The present invention is a holographic optical element comprising a volume hologram recording layer that includes a photopolymer, and at least one adjacent layer that includes a resin and is in contact with the volume hologram recording layer, wherein a diffraction grating is formed so as to extend from the volume hologram recording layer to the adjacent layer.
