Abstract:
1. An apparatus comprising: a three-dimensional display, for displaying volumetric images, comprising a three-dimensional nonlinear photoluminescent medium defining a display volume and comprising nanostructures distributed throughout the display volume; and a scanner configured to scan an output volume, where a first photon flux and a second photon flux meet, in three dimensions within the display volume, wherein the nonlinearity of the photoluminescence of the three-dimensional nonlinear photoluminescent medium is such that a photoemission from the medium where beams forming the first photon flux and the second photon flux meet is greater than a combination of a non-zero photoemission from the medium where only the beam forming the first photon flux, and not the beam forming the second photon flux is present; and a non-zero photoemission from the medium where only the beam forming the second photon flux, and not the beam forming the first photon flux is present, such that where both the beams forming the first photon flux and the second photon flux meet appear emissive compared to regions where only one of the beams forming the first photon flux and the second photon flux is present.
