Abstract
An improved power supply for alternate frame stereoscopic image presentat system includes a switch circuit for triggering two light valves mounted to present alternate left-right images to a viewer. A delay circuit using a variable pulse length monostable multivibrator permits the length of the "on" time to be adjusted to prevent light valve delays from introducing stereoscopic "ghosts".
