The Channel Multiplier Cathode-ray Tube
This paper describes a new approach to cathode-ray tube design aimed at achieving a significant depth reduction. The addressing function of the electron beam has been separated from the light generation process by a channel electron multiplier array, allowing the use of a novel deflection system based on a low-power scanning beam. Monochrome versions of the thin tube have been made with a 12" (...
متن کاملLuminance artifacts of cathode-ray tube displays for vision research.
Phosphor persistence, video bandwidth, DC restoration and high-voltage regulation affect the appearance of images presented on cathode-ray tubes (CRTs), potentially resulting in differences between nominal and actual stimuli. We illustrate these effects by measuring physical parameters of horizontal and vertical static and counter-phase flickering gratings, and we illustrate problems for vision...
متن کاملUse of computers and cathode-ray-tube displays in visual psychophysics. Part I
Computers have become so much a part of our lives that it takes a power failure to remind us of their presence. One area in which they have become indispensable is in the methodology of visual psychophysics, which forms the topic of this special issue. A typical laboratory setup for psychophysics, two decades ago, was a Maxwellianview system and an optical bench-perhaps linked to a PDP-11 `labo...
متن کاملAn intelligent system for tuning magnetic field of a cathode ray tube deflection yoke
This short communication concerns identification of the number of magnetic correction shunts and their positions for deflection yoke tuning to correct the misconvergence of colours of a cathode ray tube. The misconvergence of colours is characterised by the distances measured between the traces of red and blue beams. The method proposed consists of two phases, namely, learning and optimisation....
متن کاملWhat monitor can replace the cathode-ray tube for visual stimulation to elicit multifocal electroretinograms?
To compare a conventional cathode-ray tube (CRT) screen to organic light-emitting diode (OLED) and liquid crystal display (LCD) screens as visual stimulators to elicit multifocal electroretinograms (mfERGs), mfERGs were recorded from seven eyes of seven healthy volunteers (21 ± 2 years). The mfERGs elicited by a conventional CRT screen (S710, Compaq Computer Co.) were compared to those elicited...
