THE POSSIBILITY OF THE INTENSIFICATION AND STORAGE OF IMAGES BY MEANS OF CRYSTALLINE SCREENS,

Abstract

The report summarizes techniques then proposed or under study, suitable for storage and highly intensified projection display of scanned or unscanned electron images. The methods discussed are mainly: Control of light transmission by means of ZnS crystals which are charged by an intensity modulated scanning beam and change the polarization plane of a passing light beam in accordance with the local charge density (Ardenne), and Control of light transmission by discoloration of alkali halide crystals (dark trace tubes). The problems inherent in these two schemes are discussed which, in the first case, consist mainly in resolution limitations related to the limited breakdown field and, in the second case, in contrast limitations. With the advent of highly monochromatic intense light sources (lasers), much improved contrast rendition with dark trace tubes might be possible.
