CRT
Cathode Ray Tube.
The technical name for a picture tube or scanning tube in a flying spot telecine. An electron beam is generated, accelerated, and made to strike a phosphor coating on the inside of an evacuated glass enclosure. The phosphor glows as a result of the energy imparted by the beam. By precisely controlling the position and intensity of the electron beam, meaningful patterns are made to appear in the phosphor and are visible through the glass.
The National Film and Sound Archive of Australia acknowledges Australia’s Aboriginal and Torres Strait Islander peoples as the Traditional Custodians of the land on which we work and live and gives respect to their Elders both past and present.
