orthicon

• Ныне устаревшая передающая телевизионная трубка, использовавшаяся в ранних телевизионных камерах, где электроны, испускаемые фотоэмиссионной поверхностью пропорционально интенсивности падающего света, фокусируются на мишени, вызывая вторичную эмиссию электронов.

A now obsolete picture pickup tube used in early television cameras, where electrons emitted from a photoemissive surface in proportion to the intensity of incident light are focused onto a target, causing secondary emission of electrons.
