Abstract:
1. A method for imaging a free space three dimensional perceived image, said method comprising: obtaining a retro-reflective screen, said screen having a known non-linear light reflection pattern; obtaining an optic module comprising a doublet of Fresnel lenses; aligning at least two image projectors in a geometry so as to be able to project images off said screen and through said optic module; simultaneously calculating separate two-dimensional images for projecting by each projector, said calculated images being derived from stereopair image information regarding the object and from said pattern and said geometry; and projecting said calculated images from said projectors onto said screen such that they reflect off said screen and through said optic module to produces a three-dimensional image of said object to a viewer at a known location.
