METHODS AND SYSTEMS FOR CONTROLLING ANGULAR INTENSITY PATTERNS IN A REAL SPACE 3D IMAGE

摘要

A system for displaying one or more images in three dimensions. The system has a three dimensional illumination volume containing a gas that emits one or more types of visible light when at certain multi-photon excited states. The system includes lasers (e.g. lasers with beams outside of the visible wavelengths) that can be directed to intersect in the illumination volume to excite particles of the gas to a multi-photon excited state to emit visible light. Scanning the beam intersection (or multiple beam intersections) through the illumination volume generates three dimensional images. In some embodiments, the system includes lasers that can be directed to intersect in the illumination volume to excite particles to an intermediate state that absorbs at least a portion of the emitted radiation from particles excited to a multi-photon excited state.
