Claims
- 1. An optics system for use in creating images from coherent light in a defined volume display, said system comprising:
- a coherent light source;
- a scanner for spatially displacing individual beams of said coherent light;
- a first lens for compacting the beam width of each such spatially displaced light beam;
- a second lens for amplifying the spatial displacement of each such spatially displaced light beam without changing said compacted beam width; and
- a spinning disk defining a display volume, said spinning disk intersecting said light beam at different depths in the display volume for producing a three dimensional image.
- 2. The system as set forth in claim 1 wherein said system further comprises:
- a collimator for accepting said spatially displaced light beams and for converting said light bursts into parallel light beams.
- 3. The system set forth in claim 1 wherein said system further comprises:
- a collimator for modifying said displacement angle of said diverging light beams.
- 4. A system for presenting coherent 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, each beam 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 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.
- 5. The system set forth in claim 4 further comprising:
- a light beam divergence angle modifier for changing the angle of said divergence angle.
- 6. The system set forth in claim 4 wherein said system further includes:
- a processor for generating a plurality of signals each for controlling the depth of a light beam with said disk as well as the spatial positioning of said light beams and wherein said signals control said scanner.
- 7. The 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 such spatially displaced light beam without changing said compacted beam width; and
- 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.
- 8. The method set forth in claim 7 wherein said method further comprises:
- accepting said spatially displaced light beams and converting said light beams into parallel light bursts for introduction in said defined display volume.
- 9. A method for creating coherent light spots within a well-defined display volume to form a three dimensional image within the defined display volume, said method comprising the steps of:
- spatially displacing individual beams of coherent light, each having a particular time and spatial orientation, said spatial orientation measured as a divergence angle from a center line;
- creating a narrow waist with respect to each said displaced light beam;
- increasing each divergence angle while still maintaining each said narrow waist; and
- projecting said displaced light beams, with narrow waists, into said display volume, said light beams traveling varying distances before impacting a moving surface within said display volume.
- 10. The method set forth in claim 9 further comprising the step of:
- changing said divergence angle of each said light beam.
- 11. The method set forth in claim 10 wherein said divergence angle is changed a different amount for each said displaced light beam.
- 12. The method set forth in claim 10 further comprising the step of:
- controlling the magnitude of the total divergence of all said displaced light beams.
