All-passive transformable optical mapping near-eye display. [PDF]
Sci Rep, 2019 AbstractWe present an all-passive, transformable optical mapping (ATOM) near-eye display based on the “human-centric design” principle. By employing a diffractive optical element, a distorted grating, the ATOM display can project different portions of a two-dimensional display screen to various depths, rendering a real three-dimensional image with ...
