Abstract

A display system for creating three dimensional (3D) imagery for a viewer wearing 3D glasses such as wavelength multiplex visualization (WMV) technology glasses with a first lens passing colored light in a first range of wavelengths and with a second lens passing colored light in a second range of wavelengths. The system includes a first WMV light source outputting a first light stream onto a display surface, with the first light stream having a wavelength in the first wavelength range. The system includes a second WMV light source outputting a second light stream onto the display surface concurrently with the second light stream, with the second light stream having a wavelength in the second wavelength range. The WMV light sources are scanning lasers that each may be a scanning laser providing red, green, or blue coherent light or a full red, green, and blue (RGB) scanning laser.

First claim

We claim:

1 . A display system for creating three dimensional (3D) imagery for a viewer in a viewing space wearing 3D stereo glasses with a first lens passing colored light in a first range of wavelengths and with a second lens passing colored light in a second range of wavelengths differing from the first range of wavelengths, comprising:
a display surface facing the viewing space; a first wavelength multiplex visualization (WMV) light source outputting a first light stream onto the display surface, wherein the first light stream has a wavelength in the first range of wavelengths; and a second WMV light source outputting a second light stream onto the display surface concurrently with the second light stream, wherein the second light stream has a wavelength in the second range of wavelengths.

2 . The display system of claim 1 , wherein the first and second WMV light sources each comprise a scanning laser.

3 . The display system of claim 2 , wherein the scanning laser of each of the first and second WMV light sources comprises a scanning laser providing red, green, or blue coherent light.

4 . The display system of claim 2 , wherein the scanning laser of each of the first and second WMV light sources comprises a full red, green, and blue (RGB) scanning laser.

5 . The display system of claim 1 , wherein the first and second WMV light sources are media driven, whereby the first and second light streams provide left and right eye images of a 3D scene or object on the display surface.

6 . The display system of claim 1 , further comprising a controller operating the first and second WMV light sources based on a media file defining at least one 3D object.

7 . The display system of claim 6 , wherein the 3D object moves from a first location on the display surface to a second location on the display surface.

8 . The display system of claim 6 , further comprising a 3D set spaced apart from the display surface and wherein the first and second WMV light sources are controlled to move the 3D object from the display surface into the 3D set.

9 . The display system of claim 6 , further comprising a 3D projector projecting 3D content onto the display surface using light in the first and second ranges of wavelengths, wherein the projecting is performed concurrently with the outputting of the first and second light streams by the first and second WMV light sources, whereby the viewers concurrently perceives a blending of a pair of 3D objects.

10 . The display system of claim 9 , wherein the 3D projector comprises at least one projector implementing a narrowband-based WMV or a laser projector-based WMV.

11 . A display system for creating three dimensional (3D) imagery for a viewer in a viewing space wearing 3D stereo glasses, comprising:
a display surface facing the viewing space; a first wavelength multiplex visualization (WMV) light source outputting a first light stream onto the display surface, wherein the first light stream has a wavelength in a first range of wavelengths defined for a WMV technology; and a second WMV light source outputting a second light stream onto the display surface concurrently with the second light stream, wherein the second light stream has a wavelength in a second range of wavelengths defined for the WMV technology, wherein the first and second WMV light sources each comprise a scanning laser.

12 . The display system of claim 11 , wherein the scanning laser of each of the first and second WMV light sources comprises a scanning laser providing red, green, or blue coherent light.

13 . The display system of claim 11 , wherein the scanning laser of each of the first and second WMV light sources comprises a full red, green, and blue (RGB) scanning laser.

14 . The display system of claim 11 , wherein the first and second WMV light sources are media driven, whereby the first and second light streams provide left and right eye images of a 3D scene or object on the display surface.

15 . The display system of claim 11 , further comprising a controller operating the first and second WMV light sources based on a media file defining at least one 3D object.

16 . The display system of claim 15 , wherein the 3D object moves from a first location on the display surface to a second location on the display surface.

17 . The display system of claim 15 , further comprising a 3D set spaced apart from the display surface and wherein the first and second WMV light sources are controlled to move the 3D object from the display surface into the 3D set.

18 . The display system of claim 15 , further comprising a 3D projector projecting 3D content onto the display surface using light in the first and second ranges of wavelengths, wherein the projecting is performed concurrently with the outputting of the first and second light streams by the first and second WMV light sources, whereby the viewers concurrently perceives a blending of a pair of 3D objects.

19 . A 3D display system comprising:
a pair of 3D stereo glasses, wearable by a viewer, with a first lens passing colored light in a first range of wavelengths and with a second lens passing colored light in a second range of wavelengths differing from the first range of wavelengths; a viewing space configured for receiving the viewer; a first wavelength multiplex visualization (WMV) light source comprising a scanning laser outputting a first stream of coherent light into the viewing space, wherein the first light stream has a wavelength in the first range of wavelengths; and a second WMV light source comprising a scanning laser outputting a second stream of coherent light into the viewing space, wherein the second light stream has a wavelength in the second range of wavelengths, wherein the first and second WMV light sources are operated based on a 3D media file, whereby the first and second light streams provide left and right eye images of a 3D scene or object on the display surface.

20 . The 3D display system of claim 19 , wherein the scanning lasers are each one of a scanning laser providing red, green, or blue coherent light and a full red, green, and blue (RGB) scanning laser.
