Raster-scan cathode-ray tubes for vision research-limits of resolution in space, time and intensity, and some solutions
TLDR
Raster-based cathode-ray tubes (CRTs) are increasingly used for stimulus presentation, but their design based on consumer electronics can limit their value in vision research.Abstract:
Raster-based cathode-ray tubes (CRTs) are increasingly used for stimulus presentation. While very flexible, their design based on consumer electronics can limit their value in vision research. Here their limitations of resolution in time, space, intensity and wavelength are systematically compiled. Often, ingenious ideas can circumvent such limitations for specific experiments. Some ad-hoc solutions, as well as the more general techniques of dithering and anti-aliasing, are presented.read more

Peripheral vision and pattern recognition: a review.
TL;DR: It is reported that peripheral vision is limited with regard to pattern categorization by a distinctly lower representational complexity and processing speed than those imposed on low-level functions and by way of crowding.

Soft Tempest: Hidden Data Transmission Using Electromagnetic Emanations

TL;DR: Techniques that enable the software on a computer to control the electromagnetic radiation it transmits and a trusted screen driver can display sensitive information using fonts which minimise the energy of these emissions are discussed.

Compromising emanations: eavesdropping risks of computer displays
TL;DR: A proposal for a civilian radio-frequency emission-security standard is outlined, based on path-loss estimates and published data about radio noise levels, and a new optical eavesdropping technique is demonstrated that reads CRT displays at a distance.
