ABSTRACT:
A stereoscopic viewer system receives a synchronization signal input from a left-right stereoscopic image pair production system. A viewer system has a transmitter and a modulator associated therewith to transmit into a medium a carrier signal modulated with the synchronization signal. A transmitted signal is received by a receiver which has a demodulator to extract the synchronization signal and to supply it to switching logic. The switching logic supplies switching signals to alternately operate selectively and in accordance with the synchronizing signal each of a pair of electro-optic shutters between the maximum and minimum optical transmission state. Each shutter is positioned in the line of sight of one of the eyes of a user. The system receiving means is powered by a battery power supply.
