The Scophony Television Receiver

THE Scophony television receiver is an opticomechanical system and possesses the advantages over the purely electric systems employing a cathode ray tube that (1) larger pictures are possible without great expense ; (2) high voltages are not necessary—the voltage of a radio set is sufficient ; (3) there is lower power consumption for a given picture size. It is scarcely necessary to add that the Scophony receiver works on the B.B.C. transmission.
