Model examinations of edge effects in light-sensitive materials

The results of theoretical examinations of the dependence of edge effects o n the optical density, which influence directly the contour sharpness in th e image, are presented. Besides, the results of calculations of the influen ce of contrast in the characteristic curve of the radiation sensitive layer on the shape and properties of the limiting curve ale shown The results ob tained are presented in the form of functions of changes in the relative ed ge enhancement indicator and maximum gradient of the limiting curve as depe ndent on the level and difference of the optical density in the image and b ackground, respectively.
