ABSTRACT OF THE DISCLOSURE The appearance of depth in a two-dimensional image on a television screen or the like is achieved by optical bending means positioned between the image plane and the observer. The optical bending means produces a horizontal shift of points in the image such that the left and right eyes of the observer see a different spacing between pairs of points. The optical bending means can be in the form of a transparent undulating sheet, or can be in the form of undulations incorporated in the envelope of a television tube. It is positioned sufficiently close to the image plane that any pair of rays diverging from any point and striking the bending means continue to diverge.
