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.

System and method for rendering interactive aerial volumetric graphics and generating spatial audio using femtosecond lasers

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.

System and method for manipulating objects in a computational acoustic-potential field

An example system includes a plurality of moveable light emitters, each moveable light emitter configured to independently emit a display light from a current display location within that moveable light emitter's range of motion responsive to activation from a corresponding light activator. The system also includes a location engine to determine, for each light emitter, the current display location of that light emitter, and a mapping engine to map, for each current display location, the light activator activating the light emitter currently located at that current display location.

A novel system and method for spatial sound generation is disclosed. A system and method for generating bodiless mid-air speakers includes the steps of: generating a modulated signal by modulating an ultrasonic carrier signal with an audio signal, determining a phase delay value for each ultrasonic transducer of an array of ultrasonic transducers with respect to one or more focal points, and driving each such ultrasonic transducer with the modulated signal in accordance with the phase delay value determined for each ultrasonic transducer to generate audible sound at the one or more focal points.
