FAQ
Frequently Asked Questions
No, it is obsolete. It was replaced by solid-state charge-coupled device (CCD) and complementary metal–oxide–semiconductor (CMOS) sensors from the 1980s onward.
It's a portmanteau, likely from 'video' and 'iconoscope' (another early camera tube), or simply 'video' + the suffix '-icon'.
Primarily in historical documentaries about television, technical papers on the evolution of imaging, or in the restoration of vintage broadcast equipment.
Initially for monochrome, but colour versions were developed using striped colour filters or multiple tubes (one for each primary colour) in later, more complex cameras.
