Abstract
A projection system is provided having an aerosol generator for producing aerosol in a defined space. At least two light beam generators are arranged to direct light beams from at least two different positions onto the aerosol. Projection controls are adapted to convert three-dimensional image data into projection signals which are supplied to the light beam generators to project the three-dimensional image to become visible in the aerosol space.
Claims25
A projection system comprising:
- means for generating an aerosol of particles that are distributed uniformly in a defined three-dimensional space;
- a plurality of spaced-apart digital video beamers arranged to direct light beams to illuminate the defined space;
- and
- projection control means for converting three-dimensional image data into projection signals to be supplied to the digital video beamers, whereby the digital video beamers project the three-dimensional image so as to become visible in the defined space.

A projection system, comprising:
- means for generating an aerosol of particles that are distributed uniformly in a defined three-dimensional space;
- projection control means for generating digital projection signals from at least two perspectives of a three-dimensional object to be projected, the projection signals representing two-dimensional video signals from each perspective;
- light beam projection means for converting the projection signals into light beams representing views from the at least two perspectives, the light beam projection means having at least one digital video beamer that directs the light beams to illuminate the aerosol from at least two different positions, whereby the three-dimensional object becomes visible in the aerosol space.
A method of projecting a three-dimensional image onto an aerosol of particles, comprising:
- generating an aerosol of particles that are distributed uniformly in a defined three-dimensional space;
- converting image data of an object to be projected from at least two positions into projection signals;
- transmitting the projection signals from the at least two positions to at least two digital video beamers;
- and
- directing light beams from the at least two digital video beamers to illuminate the pace so as to project the three-dimensional image to be visible in the space.

A projection system, comprising:
- means for generating an aerosol of particles that are distributed uniformly in a defined three-dimensional space, the aerosol particles being substantially invisible to the human eye when the aerosol particles are not illuminated,
- a plurality of digital video beamers arranged to direct light beams to illuminate the defined three-dimensional space from at least two different positions, and
- projection control means adapted to convert three-dimensional image data into projection signals to be supplied to the digital video beamers, whereby the digital video beamers project the three-dimensional image so as to become visible in the defined space.
