orthicon
/ˈɔːθɪkɒn/Television. Now historical
noun
An early form of television camera tube similar to an iconoscope.
- It differs from an iconoscope in having a transparent target plate, so that the scanning beam can be made to strike normally the opposite side to that on which the image is projected, and in employing a low-velocity scanning beam, resulting in increased sensitivity and an absence of the spurious signals associated with the iconoscope. image orthicon: see image..
