Abstract

A three-dimensional imaging system comprises two image screens, for example, television monitor screens (40, 42), arranged perpendicular to one another. A beamsplitter (46), in this case a half-silvered mirror, is positioned between the two image screens (40 and 42) so as to direct both images to the same viewing location. A decoder screen (40a, 42a) is positioned between each decoder screen (40, 42) and the beamsplitter (46). Each decoder screen (40a, 42a) comprises a substrate onto which are secured, edge-to-edge, a plurality of elongate, parallel lenticular elements. The substrate is provided with a plurality of clean and opaque areas such that the decoder screen defines a plurality of alternating viewing positions at which the screen appears either wholly opaque or wholly clear. The two decoder screens (40a, 42a) are so arranged that the viewing positions at which one screen appears wholly opaque coincide with the positions at which the other decoder screen appears wholly clear. Then, when two images forming a stereoscopic pair are displayed on the two image screens (40, 42), a viewer positioned with one eye at each of two adjacent viewing positions defined by the decoder screens (40a, 42a) will see a three-dimensional image without the need for special glasses.
