Method and system for generating interactive aerial borometric image and spatial audio using femtosecond laser

摘要

SOLUTION: A plasma generator includes: a femtosecond laser light source for generating a laser pulse beam; a processor for generating a computer generated hologram; a spatial light modulator for modulating the laser pulse beam according to the computer generated hologram; and a three-dimensional scanner optically connected to the spatial light modulator. The three-dimensional scanner includes a lens directing the modulated laser pulse beam on one or more focuses in the air and focusing the modulated laser pulse beam. The modulated laser pulse beam has visibility, audibility and a tactile luminous effect on one or more focuses.EFFECT: A system for generating an interactive aerial volumetric image and spatial audio using femtosecond laser is addressable at the same time, can be combined with a computer generated hologram, can provide a near-field laser plasma display, can provide a tactile plasma interaction, and can provide immersive audio.SELECTED DRAWING: None
