Single monitor stereoradiological television system using PLZT electrooptic shutters

A new family of materials consisting of lead lanthanium zirconate titanate (PLZT) has evolved from recent advances in ferroelectric ceramics. PLZT electrooptic ceramics may be used as electronically triggered high-contrast optical shutters in lightweight stereoscopic viewing devices. A PLZT electrooptic shutter stereoradiology system in which dual x-ray tubes are used to generate stereo pairs of fluoroscopic images is presented. This system requires only a single television monitor for stereoscopic viewing by one or more observers. The viewer which contains the optical shutters is compact, light-weight, and can be attached easily to normal eyeglasses.
