The Iconoscope, first
made by RCA, is the earliest functional all-electronic TV camera tube,
invented by Vladimir Zworykin in 1929, first presented in 1933, and patented
in 1939. Followed by the Super-Iconoscope which bears
close similarities to the English made Super-Emitron
(by EMI), it was mainly used in American Broadcasting stations as from 1936 and as late as 1946, but
suffered from the need for strong illumination. It was superseded by the Image Orthicon tube in 1946. Special models of this tube,
somewhat smaller in size, were particularly developed and used
in air-borne cameras in bombers during Worl War II. |
