Claims
- 1. A display system, the display system comprising:
a screen assembly comprising: a thin projection screen; and a plurality of spherical sections, such that the sections form substantially a sphere with the projection screen held therein, the spherical sections being transparent, rigid, and hollow, and the projection screen being substantially equally reflective and transmissive.
- 2. The display system of claim 1, wherein the screen assembly rotates symmetrically about an axis.
- 3. The display system of claim 2, further comprising:
a data source that provides images for volumetric display; a projection optics subsystem that projects a series of images from the data source for display on the projection screen, such that the series as perceived by a viewer appears volumetric; and a control electronics subsystem that perform operations on data including data from the data source and coordinates operations of the screen assembly, the data source, and the projection optics.
- 4. The display system of claim 3, wherein the plurality of spherical sections includes two truncated spherical halves.
- 5. The display system of claim 3, wherein the projection screen lies in a plane which includes the axis about which the screen assembly rotates.
- 6. The display system of claim 3, wherein the projection screen is substantially disk shaped.
- 7. The display system of claim 6, wherein the projection screen has a truncation corresponding to a truncation of the plurality of spherical sections.
- 8. The display system of claim 3, wherein the projection screen is helix shaped.
- 9. The display system of claim 3, wherein the projection screen includes vellum.
- 10. The display system of claim 3, wherein the projection screen includes a layer of paint disposed on a thin substrate.
- 11. The display system of claim 3, wherein the projection screen includes a sheet of microspheres having optical properties.
- 12. The display system of claim 3, wherein the projection optics subsystem projects two-dimensional images.
- 13. The display system of claim 3, wherein the projection optics subsystem projects one-dimensional images.
- 14. The display system of claim 3, wherein the projection optics subsystem projects zero-dimensional images.
- 15. The display system of claim 3, wherein the control electronics subsystem performs operations on data from the data source to compensate for positional differences between the screen assembly and the projection optics subsystem.
- 16. The display system of claim 4, wherein the rotating screen assembly is included within a transparent viewing dome.
- 17. A method for volumetric display, the method comprising:
providing a rotating screen assembly, the screen assembly comprising a thin projection screen and a plurality of spherical sections, such that the sections form substantially a sphere with the projection screen held therein, the spherical sections being transparent, rigid, and hollow, and the projection screen being substantially equally reflective and transmissive; providing a data source that provides images for volumetric display; projecting a series of images from the data source for display on the projection screen, such that the series as perceived by a viewer appears three-dimensional; and coordinating the rotating screen assembly, the data source, and the projection via a control electronics subsystem that perform operations on data including data from the data source.
- 18. The method of claim 17, wherein the plurality of spherical sections includes two truncated spherical halves and the projection screen is substantially disk shaped.
- 19. A display system, the display system comprising:
a screen assembly comprising: a thin projection screen; and a plurality of sections, such that the sections form a surface having substantially uniform symmetry about an axis, the projection screen held within the surface, the sections being transparent, rigid, and hollow, and the projection screen being substantially equally reflective and transmissive.
