Abstract

Chapters 11, 12, and 14 reviewed the main architectures used today in see-through NTE displays: - Optical engine coupled to a free-space optical combiner, - Optical engine coupled to a freeform TIR prism optical combiner, and - Optical engine coupled to a waveguide optical combiner. All of these architectures require macro-, micro-, or even nanooptical elements (lenses, reflectors, waveguides, MLAs, gratings, holograms, etc.) and abide by the law of etendue to build a specific combination of FOV, angular resolution, and an eyebox (see Chapter 8 on how to circumvent it).
