GT&E TRANSMITS TV VIA LASER BEAM: Long-range look at unique TV system with potential for simultaneously transmitting more than 160 TV programs, compared with 10 via conventional techniques, was furnished by GT&E lost week. In what is believed to be a "first," lob model of new communications system transmitted & received TV pictures on a light beam generated by a laser device.
Cautioning that 5-10 years of research & development are required before system "can be considered for application on a practical basis," GT&E Lobs Pres. Dr. Lee L. Davenport pointed out : "The method of optical loser communications demonstrated establishes the ultimate potential of optical links [but] a number of scientific breakthroughs are required before earth-to-eorth communications can be considered feasible." Among major problems to be solved; long-distance transmission of laser beams.
In demonstration at GT&E Bayside, L.I. labs, conventional TV signal & continuous microwave signal were applied to traveling wove tube. Resultant video-modulated microwave signal was fed into electro-optic light modulator through which laser beam was being projected. When laser beam emerged from modulator it carried video information superimposed on microwave signal. Transmitter beam was relayed to experimental optical receiver in some room, and the detected video picture was shown on TV monitor.
Key receiver component is Sylvania-developed traveling wove tube photodetector. It converts laser light signals into microwaves which ore amplified, demodulated & displayed on TV picture tube. Photodetector was designed by Dr. Burton J. McMurtry, head of Sylvonia Microwave Device Div.'s optical device dept., and Prof. Anthony E. Siegmon, Stanford U. electrical engineering dept.
