Retinal projection is required for xR applications that can deliver immersivevisual experience throughout the day. If general-purpose retinal projectionmethods can be realized at a low cost, not only could the image be displayed onthe retina using less energy, but there is also the possibility of cutting offthe weight of projection unit itself from the AR goggles. Several retinalprojection methods have been previously proposed; however, as the lenses andiris of the eyeball are in front of the retina, which is a limitation of theeyeball, the proposal of retinal projection is generally fraught with narrowviewing angles and small eyebox problems. In this short technical report, weintroduce ideas and samples of an optical system for solving the commonproblems of retinal projection by using the metamaterial mirror (planesymmetric transfer optical system). Using this projection method, the designingof retinal projection can becomes easy, and if appropriate optics areavailable, it would be possible to construct an optical system that allows thequick follow-up of retinal projection hardware.

How could we ignore the lens and pupils of eyeballs: Metamaterial optics for retinal projection
