<p>An optical generator comprises a light source (lamp) 1 within an open cylinder 3 rotatable about its axis and including at least part through which an optical receptor 10 such as a digital micro mirror device (DMD) can be illuminated as the cylinder 3 rotates. Also. there is means 6 for driving coolant air through the cylinder past the source, either by fan blades within the cylinder or by means of an external fan. The cylinder 3, which may be hexagonal, can provide colour-sequenced light directed out to a beam-splitter prism onto a digital micromirror device, which displays an image through electrical means, providing a micro video/data projector. The cylinder may comprise partly coloured glass polarized in different directions, corresponding to stereoscopic passive polarised glasses, for stereoscopic 3D projection (see Figures 7-9).</p> |
