Like much work on displays adopting HOEs, Kogelnik’s [1969] coupled-wave theory provides a theoretical background for volume grating-based holograms. A fully recorded HOE can be modeled as a periodic volume grating, which makes use of strong resonant difraction known as Bragg difraction. If the thickness of the grating structure is sufciently large at the molecular level, all orders of the difracted beam can be eliminated with the exception ofa single order with strong selectivity to Bragg matched light. With this knowledge of volume gratings, an HOE can be described as a group of planar gratings of infnitesimal lateral size in space. By modeling this optical element in tools such as Matlab and Zemax, ray tracing-based simulation with difractive element can provide precise and straightforward results for both peripheral display performance and beam shaping experiments.

Figure S1 shows the schematic diagram of our HOE simulator and essential elements for the display. Each optical element, including the user/viewer has several parameters. For example position, size, thickness of the photopolymer, average refractive index ( n 0 ), and refractive ∗ Also with Seoul National University.
