vidicon

(ˈvɪdɪˌkɒn)
n
(Broadcasting) a small television camera tube, used in closed-circuit television and outside broadcasts, in which incident light forms an electric charge pattern on a photoconductive surface. Scanning by a low-velocity electron beam discharges the surface, producing a current in an adjacent conducting layer. See also Plumbicon
