Abstract
Real three-dimensional images make their full impact only if seen over a wi de field-of-view, but those on present three-dimensional a ideo displays ra rely span more than 20. The field-of-view of a multiprojector three-dimensi onal display can be expanded to 90 or more by a circularly symmetric field lens, and the dark zones typically present between the views of a multiproj ector system can be eliminated without ghosting by using a pinhole projecto r equivalent arrangement and a precise diffuser. A planarised version of th e optics has been demonstrated, and if combined with a waveguide screen and microdisplays may give an inexpensive three-dimensional display which has a large, flat screen and wide field-of-view.
