Scanning laser 3D display system.

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.

Background

BACKGROUND(1) 1. Field of the Description(2) The present description relates, in general, to three dimensional (3D) projection and display technology including 3D glasses or stereo glasses worn by viewers to perceive 3D imagery, and, more particularly, to 3D stereo display systems that are adapted for creating 3D effects or imagery with 3D content or media but without the need for conventional 3D projectors.(3) 2. Relevant Background(4) Recently, there has been an increased interest in providing movies and other image-based content to viewers in 3D form, and there has been significant research in the past on technologies to produce 3D imagery. Most 3D technologies require the viewers to wear 3D glasses (or other headgear or other filters, which will be labeled “3D glasses” herein) such that left eye images are received by their left eye and right eye images are received by their right eyes. The combination of these right and left eye images is perceived by the viewers as 3D images or imagery (or stereo images).(5) Polarization and wavelength multiplex visualization (“WMV”) are two main types of 3D technologies that are in widespread use in cinema applications and in other entertainment venues including amusement or theme parks (e.g., in 3D rides, 3D displays, and other park attractions). In each of these 3D technologies or systems, the displays or projection systems have relied upon or targeted raster-based displays such as video projection, film, displays, and the like.(6) W

Claims

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 an area of the display surface, wherein the first light stream has a wavelength in the first range of wavelengths; a second WMV light source outputting a second light stream onto the area of the display surface concurrently with the first light stream, wherein the second light stream has a wavelength in the second range of wavelengths; and a 3D projector projecting 3D content onto the display surface in the area using a third light stream with light in both 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, wherein the first and second WMV light sources each comprises a scanning laser, wherein the first and second light streams comprise coherent light producing a first one of the 3D objects in the pair of 3D objects via particle-based media, and wherein the third light stream produces a second one of the 3D objects in the pair of 3D objects via pixel-based media. 9. 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; a second WMV light source outputting a second light stream onto the display surface concurrently with the first light stream, wherein the second light stream has a wavelength in a second range of wavelengths defined for the WMV technology; and a 3D projector projecting 3D content onto the display surface using a third light stream differing from the first and second light streams and with non-coherent light in the first and second ranges of wavelengths, wherein the first and second WMV light sources are external to and spaced apart from the 3D projector, 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 viewer concurrently perceives a blending of a pair of 3D objects, and wherein the first and second WMV light sources each comprises a scanning laser providing coherent light. 21. 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; a second WMV light source outputting a second light stream onto the display surface concurrently with the first light stream, wherein the second light stream has a wavelength in a second range of wavelengths defined for the WMV technology, wherein a combination of the first and second light streams provides a first 3D object, and wherein the first and second WMV light sources each comprises a scanning laser; a 3D projector projecting a third light stream, differing from the first and second light streams, onto the display surface to provide a second 3D object with light have wavelengths in both the first and second ranges of wavelengths; and 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, wherein the 3D set comprises reflective elements comprising material with a reflectivity of less than about 20 percent, and wherein the WMV light sources are controlled to provide the first and second light streams onto the area of the display surface at a first level of brightness and onto the 3D set at a second level of brightness greater than the first level of brightness.
