Television pickup tubes which use cathode-ray beam scanning, although only one class of television pickup devices, may be made in a variety of ways, a number of which are described in this paper. In these tubes, the function of the electron beam is to release secondary electrons from the target, the number escaping being modulated by electrostatic fields, magnetic fields, orientation of electrodes or changes in the secondary emission ratio of the target. The Iconoscope is a well-known example… Expand
Television Pickup Tubes Using Low-Velocity Electron-Beam Scanning
Television pickup tubes which use a low-velocity electron beam for scanning a photosensitive target offer the possibility of avoiding some of the limitations of devices which use a high-velocityExpand
The Image Orthicon-A Sensitive Television Pickup Tube
The image orthicon is a television pickup tube incorporating the principles of low-velocity-electron-beam scanning, electron image multiplication, and signal multiplication. It closely approaches theExpand
Video Storage by Secondary Emission from Simple Mosaics
It has been found that the derivation of a video signal in an iconoscope by scanning does not involve bringing each element of the mosaic into an electron-exchange equilibrium while under the beam.Expand
Recent Improvements in the Design and Characteristics of the Iconoscope
The sensitivity and picture-signal output of iconoscopes have recently been increased by a factor of two or three times. The spectral response of the newer tubes more dosely resembles that of the eyeExpand
High-Temperature Operation Method for Image Pickup Tube
This paper proposes a new operation method for an image pickup tube under high-temperature conditions. The landing energy of an electron beam is set at a value for the secondary electron yield aboveExpand
The Image Iconoscope
An iconoscope having increased sensitivity is to be desired for purposes of improving studio conditions, making possible more universal outdoor work, and permitting greater depths of focus. The newExpand
A decade of progress in the use of electronic tubes: Part I — In the field of communication
THE dependency of the art of communication on the science of electronics is so great as to make a review of progress in electronics almost of necessity a review of the field of communications itself.Expand
Rethinking Image Sensor Noise for Forensic Advantage
TLDR
Analysis of the diversity of sources of noise remaining within the noise residue shows that further insight is possible within a unified sensor pattern noise concept which opens the field to approaches for obtaining fingerprints utilising fewer resources with comparable performance to existing methods.

The Piecemeal Rationality of Application-Oriented Research
The Plumbicon is a television camera pickup tube which was developed by the Philips Research Laboratories.1 It was made public in 1962 and even today is considered the ultimate in pickup tubeExpand
