Vidicon
A vidicon tube is a video camera tube design in which the target material is a photoconductor. The vidicon was developed in 1950 at RCA by P. K. Weimer, S. V. Forgue and R. R. Goodrich as a simple alternative to the structurally and electrically complex image orthicon. While the initial photoconductor used was selenium, other targets—including silicon diode arrays—have been used. Vidicons with these targets are known as Si-vidicons or Ultricons.
