Influence of the luminance spatial non-homogeneities of a display monitor on the contrast sensitivity function determination

摘要

The application of computer devices equipped with video monitors both in clinical practice and human vision research has become widespread. These devices offer great advantages over other traditional methodologies(such as printed tests)because they facilitate the variation of the experiment parameters or the design of new psychophysical experiences. The aim of this paper is to determine the degree to which spatial inhomogeneity affects the generation of sinusoidal gratings on a video Display.
