Engineering:Fog display
From HandWiki
A fog display, fog screen, vapor screen or vapor display is a system that uses haze machines or water vapor to create a semi-transparent wall, or "curtain" of suspended particles which trapped in a thin sheet (laminar flow) of air and are illuminated by a projector,[1] in order to produce a display whose images seem to float in mid air.[2] Several commercial systems exist, such as FogScreen, Displair and Heliodisplay. There is also an open-source variant being developed called Hoverlay II[3][4]
This system can be expanded using multiple projectors to create a three-dimensional image, thus becoming a volumetric 3D display.[5]
