摘要:
A system for achieving a three-dimensional (3D) volumetric display by using a successive stack of transparent two-dimensional planar layers each having light-absorbing elements representing contours as dark features associated with individual respective slices through a three-dimensional object in a direction perpendicular to the plane of view of each of the planar layers so that the combined assembled volumetric display when viewed achieves a volumetric display which may be reconfigured using physical, chemical, electronic and computer-assisted means, so as to effect a dynamic volumetric display.
摘要:
A coating is disclosed for use with GaAs and other Type III-V semiconductor substrates, comprised of a rare-earth element or elements and a non-rare-earth element or elements, that forms an improved graded junction which is thermally stable, has satisfactory electrical properties and is resistant to the through migration of Ga or As.
