  • Patent number: 10197904
    Abstract: One embodiment relates to a method for creating a fast vanishing light scattering surface/volume to which an image is projected. The method includes: creating two portions of atomized particles of a given particle size that does not allow an incident light having a visible spectrum from being scattered, reflected and/or dissipated; and ejecting these two portions of the atomized particles from two opposite directions towards each other. The atomized particles collide/contact with each other to aggregate, thereby creating the fast vanishing light scattering surface/volume at a specific spatial region in which the aggregated particles allow the incident light to be scattered, reflected and/or dissipated.
