3DIcon is currently developing 3D projection and display technologies that produce full colour 360 degree volumetric images.
One of the possible applications envisaged for this technology could be the implementation of an Air Traffic Control system that allows a user to view the entire 3D airspace and its contents in real-time.
CSpace

The research team, working at the University of Oklahoma, is developing CSpace a Volumetric Imaging System which will use a clear volumetric medium within which an invisible nano-size material is dispersed. A 3D image is rendered when laser beams directed into the image space excite the nano-materials to emit visible light to construct the image.
So far, the team has been able to create nano-size crystals which exhibit green fluorescence and have been able to embed these particles within a clear host material.
3D-SVD

3D-SVD (swept volume display) is another technology currently under development. In this case, a three-dimensional image is formed by illuminating a rapidly moving circular screen sweeping a spherical volume. Voxels are rendered at precise locations within the volume over a period of time resulting in a 3D image due to persistence of vision.
Further work will look at improving the resultant image so that it appears more solid with negligible flicker.
