Abstract

Field-sequential stereoscopy, an increasingly accepted means of displaying three-dimensional visual images, is reviewed. The conventional electrooptic shutter devices used for viewing such displays employ either twisted nematic liquid crystals or PLZT ceramics. Both of these methods suffer the drawback of severe reduction in the brightness of the display image being observed. To overcome this problem, a field-sequential stereoscopic viewing apparatus employing light-scattering cholesteric liquid crystals is proposed. Advantages of this device include minimal reduction in image brightness, full colour and reduced visual fatigue.
