Abstract: A novel system and method based on three-dimensional acoustic-manipulation technology is disclosed. By changing the distribution of an acoustic-potential field generated by ultrasonic phased arrays, objects can be levitated and animated. Various distributions of acoustic-potential fields can be generated in accordance with the present invention, including acoustic-potential fields having arbitrary shapes, including any three-dimensional shapes. One or more ultrasonic phased arrays surrounding a workspace can be used to generate standing waves of various shapes to provide the acoustic-potential fields. Objects can be suspended at the nodes of the acoustic-potential field so that the ultrasound distribution (i.e., the desired arbitrary shape) is visualized. The system and method can be used to realize floating screen or mid-air raster graphics, mid-air vector graphics, and interaction with levitated objects. The system and method can also be used in other applications, including cleaning applications.

Abstract: A plasma generator including: a femtosecond light source that generates a laser pulse beam; a processor that computes a computer generated hologram; a spatial light modulator that modifies the laser pulse beam in accordance with the computer generated hologram; a three dimensional scanner optically coupled to the spatial light modulator to direct the modified laser pulse beam to one or more focal points in air; and a lens that focuses the modified laser pulse beam. The modified laser pulse beam induces a light emission effect at a one or more focal points that can be visible, audible, and palpable.
