Claims
- 1. A system for presenting light beams to a defined volume such that the presented beams will impact the volume at different distances from the light source to form a three dimensional image within the defined volume, said system comprising:
- a scanner for spatially displacing individual beams of coherent light into beams, each having a particular time and spatial orientation, said spatial orientation measured as a divergence angle from a center line;
- a first positive lens for creating a narrow waist with respect to each said light beam emerging from said scanner;
- a second negative lens for increasing each divergence angle while still maintaining each said narrow waist;
- a spinning disk defining a display volume, said spinning disk intersecting said light beams at different depths in the display volume for producing a three dimensional image; and
- a light beam divergence angle modifier for changing the angle of said divergence angle wherein said modifier is selectively controllable.
- 2. A system for presenting light beams to a defined volume such that the presented beams will impact the volume at different distances from the light source to form a three dimensional image within the defined volume, said system comprising:
- a scanner for spatially displacing individual beams of coherent light into beams, each having a particular time and spatial orientation, said spatial orientation measured as a divergence angle from a center line;
- a first positive lens for creating a narrow waist with respect to each said light beam emerging from said scanner;
- a second negative lens for increasing each divergence angle while still maintaining each said narrow waist; and
- a spinning disk defining a display volume, said spinning disk intersecting said light beams at different depths in the display volume for producing a three dimensional image;
- wherein said scanner is selectively controllable.
- 3. A method of operating an optic system for creating images from coherent light in a display volume defined by a spinning disk, said method comprising the steps of:
- accepting coherent light beams;
- spatially displacing individual light beams of said coherent light;
- compacting the beam width of each such spatially displaced light beam;
- amplifying the displacement angle of each spatially displaced light beam without changing said compacted beam width;
- projecting each said light beam, which has had the beam width compacted, into said display volume, intersected by the spinning disk, and forming a three dimensional image; and
- modifying said displacement angle of said diverging light beams.
- 4. A method of operating an optic system for creating images from coherent light in a display volume defined by a spinning disk, said method comprising the steps of:
- accepting coherent light beams;
- spatially displacing individual light beams of said coherent light;
- compacting the beam width of each such spatially displaced light beam;
- amplifying the displacement angle of each spatially displaced light beam without changing said compacted beam width;
- projecting each said light beam, which has had the beam width compacted, into said display volume, intersected by the spinning disk, and forming a three dimensional image;
- generating a plurality of signals related to the location of the variable focal plane; and
- controlling said spatial displacement of said beams in response to said generated signals.
