A Fluorescent Mid-air Screen

The Fog Screen can create high-quality walk-through images onto a translucent fog plane with rear-projection, so that they appear to float in mid-air. Projector's hotspot may distract viewers, but here we present a method based on fluorescence and front-projection to apparently remove the projector's light altogether. The fluorescent Fog Screen can create even more magical images than the standard Fog Screen.
