Stereoscopic display apparatus |
摘要 |
<p>A stereoscopic 3D display comprises a light source 2 and condenser optics 4 which direct light through a spatial light modulator 41 and a polarisation modulator 42. Each of the devices 41 and 42 is pixellated with the pixels of one device being optically aligned with respective pixels of the other device. Each pixel of the spatial light modulator 41 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 42 is controlled so as to supply output light with a polarisation angle given by the arc-tangent of the quotient of the pixel amplitudes of the stereoscopic images. Polarising glasses 40 with suitably aligned polariser lenses allow an observer to perceive the 3D effect, for instance on a polarisation preserving screen 1 on which the encoded stereoscopic image is projected by projection optics 8. <IMAGE></p> |
