Abstract

Volume holograms exhibit unique optical characteristics based on selective diffraction dependent on the state of incident light. For example, they are applicable to holographic data storage for ultra-high-definition video, holographic optical elements utilizing selective diffraction, super-resolution imaging, and optical combiners for AR head mount display. Since optical combiner is realized by using a partially reflective mirror, the larger the area to be displayed, the larger volume the mirror occupies. By using a holographic optical element, the volume occupied by the optical combiner can be decreased. However, thin holographic optical element exhibits strong wavelength dependence, so that multiple holographic optical elements are used for full color display. On the other hand, optical expansion system is important to decrease the volume of display system. In this study, a cylindrical wave volume holographic optical element was investigated to use as an optical combiner.
