Photoconduction
| Глоссарий по визуальному контролю и осмотру |
Method by which a vidicon television camera tube produces an electrical image, in which the conductivity of the photosensitive surface changes in relation to the intensity of the light reflected from the scene focused onto the surface. compare photoemission.

Фотопроводимость, русский
, увеличение электрической проводимости полупроводника под действием света. причина фотопроводимости - увеличение концентрации носителей заряда - электронов в зоне проводимости и дырок в валентной зоне.

Television, английский
- Телевидение; телевизионный
- The electronic transmission of pictures and sounds.
- Телевидение
- An electronic system of transmitting transient images of fixed or moving objects together with sound through space by an apparatus that converts light and sound into electrical waves and reconverts them into visible light rays and audible sound.
Electrical, английский
Conductivity, английский
- Conductivité
- The rate at which heat is transmitted through a material.
- A term used in describing the capability of a material to carry an electrical charge. usually expressed as a percentage of copper conductivity copper being one hundred (100%) percent. conductivity is expressed for a standard configuration of conductor.
- Проводимость
- Удельная электропроводность; удельная электрическая проводимость
- Parameter used for characterising hydrogeological conditions, more
- This is the inverse of resistance, and refers to the ability of a conductor to carry current.
Photosensitive, английский
Photoemission, английский
- Method by which an image orthicon television camera tube produces an electrical image, in which a photosensitive surface emits electrons when light reflected from a viewed object is focused on that surface. compare photoconduction.

Photometric brightness, английский
- Luminance of a light source.
- See luminance.
Optic disk, английский
- Area in the retina through which the fibers from the various receptors cross the inner (vitreous humor) side of the retina and pass through it together in the optic nerve bundle. this transitional area is completely blind.
