Metalens array to enable next-generation true-3D near-eye displays

https://phys.org/news/2024-01-metalens-array-enable-generation-true.html

"pixel-level light manipulation... minimum feature size 100 nm, maximum nanostructure height 500 nm... high-refractive-index nanoimprint glue... low-cost, large-area nanoimprint fabrication process... EIA average 67 FPS exploiting invariant voxel-pixel mapping... see-through effect... true-3D NED with meta-optic and II display combination... polarization multiplexing allowing depth of field extension... freeform phase profiles precisely compensate for field-dependent aberration recorded in slim metalens array... AR, VR"
