Aerial Mid-Air Plasma Projection
< SCIENTIFIC DOCUMENTATION & FIELD STUDY >
EXECUTIVE CORE METHODOLOGY
How high-frequency femtosecond lasers plasma-excite nitrogen and oxygen molecules to generate actual mid-air touchable pixels without static screens.
Aerial mid-air plasma projection represents a screenless volumetric display methodology, creating physical light coordinates hovering directly in thin air without utilizing projection foils or physical enclosures.
The technology uses high-frequency infrared femtosecond lasers. These lasers emit pulses of light focused on precise points in space. At these focal coordinates, the intense optical field ionizes nitrogen and oxygen molecules in the air, creating glowing, microscopic plasma pixels.
By scanning these focal points rapidly in three dimensions, the system draws solid 3D wireframe models in mid-air. These plasma pixels are touchable; interrupting the light path generates a minor thermal pop on the user’s skin, delivering passive haptic feedback.
