Abstract
Methods and systems may provide for 3D volumetric displays. Such 3D volumetric displays may include a transparent enclosed volume holding a gas as a stationary gain medium. A scanning mirror may direct a light beam from a light source. A voxel projector may receive the light beam from the scanning mirror and may project an expanded beam into a volume of the stationary gain medium. Changes in the X and Y orientation between the light beam from the scanning mirror and the voxel projector results in relatively larger changes in the X and Y dimension of the expanded beam that is projected into the volume of the stationary gain medium to produce a 3D image.

An apparatus for 3D volumetric display, comprising:
- a transparent enclosed volume, wherein the transparent enclosed volume holds a gas as a stationary gain medium;
- a light source;
- a scanning mirror configured to direct a light beam from the light source in an X and a Y dimension;
- and
- a voxel projector configured to receive the light beam from the scanning mirror and project an expanded beam into the transparent enclosed volume of the stationary gain medium, wherein the voxel projector is a rotatable diffractive plate, and wherein a change in a radial location of the light beam on the voxel projector controls changes in the Y dimension of the expanded beam that is projected into the volume of the stationary gain medium.
A system, comprising:
- a vehicle;
- a 3D volumetric display coupled to the vehicle, the 3D volumetric display comprising:
- a transparent enclosed volume, wherein the transparent enclosed volume holds a gas as a stationary gain medium;
- a light source;
- a scanning mirror configured to direct a light beam from the light source in an X and a Y dimension;
- and
- a voxel projector configured to receive the light beam from the scanning mirror and project an expanded beam into the transparent enclosed volume of the stationary gain medium, wherein the voxel projector is a rotatable diffractive plate, and wherein a change in a radial location of the light beam on the voxel projector controls changes in the Y dimension of the expanded beam that is projected into the volume of the stationary gain medium.
A method for 3D volumetric displays, comprising:
- holding a gas, via a transparent enclosed volume, as a stationary gain medium;
- emitting a light beam, via a light source;
- directing the light beam from the light source in an X and a Y dimension, via a scanning mirror;
- and
- receiving the light beam from the scanning mirror and projecting an expanded beam into the transparent enclosed volume of the stationary gain medium, via a voxel projector, wherein the voxel projector is a rotatable diffractive plate, and wherein a change in a radial location of the light beam on the voxel projector controls changes in the Y dimension of the expanded beam that is projected into the volume of the stationary gain medium.
