Feasibility of a Free-Space 3D Display Using Liquid-Gas Two-Phase Flow
Details
Feasibility of a free-space 3D display using liquid-gas two phase-flow were studied. Thin/flat smoke (liquid-gas multi-phase) screen was blown out from a narrow slit and mechanically scanned to project 3D video images. In order to maintain the flatness of the screen, a narrow nozzle for smoke flow was sandwitched by two wider nozzles for air flows in order to extend the potential core. The properties of projected images, such as reflection rate and resolution, and deformation of the screen due to mechanical scanning were evaluated. Image data generation and projection were discussed to project real 3D images. As a reault, 3D images were displayed in free-space, although the scan rate was low.
