System and methods for angular slice true 3-D display

A system comprising:

• one or more 2-D image projectors;
• and
• a display screen optically coupled to said 2-D image projectors;
• wherein the 2-D image projectors are configured to project individual 2-D images substantially in focus on the display screen;
• wherein each pixel from each of the 2-D images is projected from the display screen into a small angular slice to enable a viewer observing said display screen to see a different image with each eye, wherein the image seen by each eye varies as the viewer moves his or her head with respect to the display screen;
• wherein the display screen is diffusive with a diffusion angle α (full-width at half-maximum, FWHM) in the horizontal plane and a diffusion angle β (FWHM) in the vertical plane;
• wherein the 2-D image projectors are arranged as elements in a horizontal and vertical matrix with a horizontal displacement angle substantially equal to α/2 between adjacent horizontal elements of the matrix and vertical displacement angle substantially equal to β/2 between adjacent vertical elements of the matrix, wherein the horizontal and vertical displacement angles are measured from the display screen.
