Alphabetical list of terms

Record 1 2013-06-20

English

Subject field(s)
  • Vacuum Tubes (Electronics)
  • Television (Radioelectricity)
DEF

A television camera tube in which an electron image is produced by a photoemitting surface and focused on one side of a separate storage tube that is scanned on its opposite side by a beam of low-velocity electrons.

OBS

Electrons that are reflected from the storage tube, after positive stored charges are neutralized by the scanning beam, form a return beam which is amplified by an electron multiplier.

OBS

image orthicon: term officially approved by the Electronics and Telecommunications Terminology Committee.

French

Domaine(s)
  • Tubes et lampes (Électronique)
  • Télévision (Radioélectricité)
OBS

orthicon à transfert d'image; image orthicon : termes uniformisés par le Comité d’uniformisation des termes de l’électronique et des télécommunications (CUTEL).

Spanish

Campo(s) temático(s)
  • Tubos de vacío (Electrónica)
  • Televisión (Radioelectricidad)

Record 2 2013-05-29

English

Subject field(s)
  • Vacuum Tubes (Electronics)
  • Television (Radioelectricity)
DEF

A camera tube in which a beam of low-velocity electrons scans a photoemissive mosaic that is capable of storing a pattern of electric charges.

CONT

Electronic equipment suitable for use in optical measurements include a high speed electronic shutter, a nanosecond oscilloscope, an orthicon image tube with associated equipment, and various power supplies suitable for use with photomultipliers, flash tubes, etc.

OBS

Has higher sensitivity than [an] iconoscope.

OBS

orthicon: term officially approved by the Electronics and Telecommunications Terminology Committee.

French

Domaine(s)
  • Tubes et lampes (Électronique)
  • Télévision (Radioélectricité)
DEF

Appareil de prise de vues dérivé de l'iconoscope et dans lequel le faisceau d'électrons permettant le balayage frappe l'écran perpendiculairement.

OBS

orthicon : terme uniformisé par le Comité d’uniformisation des termes de l’électronique et des télécommunications (CUTEL).

Record 3 2011-04-18

English

Subject field(s)
  • Television (Radioelectricity)
DEF

A camera tube in which a charge image corresponding to the optical image input grows in magnitude on the target until neutralised by the scanning beam.

OBS

This occurs in all the camera tubes such as the iconoscope, image iconoscope, orthicon, image orthicon and vidicon which have been successfully used in television services. Storage occurs by virtue of the capacitance of the target and it brings about a considerable increase in the sensitivity of the tube. In fact it was not until the advantage of the storage principle was appreciated that tubes sensitive enough for use in television services became possible.

OBS

storage camera tube: term officially approved by the Electronics and Telecommunications Terminology Committee.

French

Domaine(s)
  • Télévision (Radioélectricité)
OBS
