Abstract
A stereoscopic 3D display comprises a light source and condenser optics which direct light through a spatial light modulator and a polarisation modulator. Each of the modulators is pixellated with the pixels of one modulator being optically aligned with respective pixels of the other modulator. Each pixel of the spatial light modulator is controlled so as to provide a light amplitude which is equal to the square root of the sum of the squares of the corresponding pixels of the stereoscopic images. Each pixel of the polarisation modulator is controlled so as to supply output light with a polarisation angle give by the arc-tangent of the quotient of the pixel amplitudes of the stereoscopic images. Polarising glasses with suitably aligned polariser lenses allow an observer to perceive the 3D effect, for instance on a polarisation preserving screen on which the encoded stereoscopic image is projected by projection optics.
