<p>Method and arrangements for the viewing and formation of stereoscopic pictures including pictures from television screens. A method of viewing a stereoscopic pair of images in which the image for one eye (10) is viewed by reflection from a surface (17) of a prism (8) and the image for the other eye (9) is viewed directly through that surface (17) of the prism (8), the spacing between the eyes (9, 10) in relation to the prism (8) being such that the angle at which the said one eye (10) sees the first image is such that complete internal reflection occurs at the surface (17) but the angle at which the other eye (9) sees the image is such that substantial internal reflection does not occur. A pair of prisms (8, 115) abut one another along a common side (17, 117) so that for viewing an image directly and without reflection the light path through the prisms (8, 115) is approximately the same the whole way across that image thereby avoiding distortion as a result of the light from one part of the image seen by direct viewing having to pass through a greater thickness of prism material than the light from another part of that image.</p> |
