Volumetric display with dust as the participating medium
First Claim
1. An apparatus for producing a volumetric display comprising:
- a scanning collimated light source that creates an image by illuminating a suspension of light-scattering particles in an optically transparent medium with a collimated beam, where the brightness of the collimated beam is modulated at each moment in time by an amount that is dependent upon the momentary direction of the beam and also on the distance of the scattering particle from the light source encountered by the beam at that moment, the beam includes a first, monitoring, collimating beam used to detect the presence of the particle, and a second, illuminating, beam is used to illuminate the detected particle.
