Model examinations of edge effects in light-sensitive materials

Rajkowski B., Nowak P.

Optica Applicata

2001

Vol. 31, nr 1

185-191

The results of theoretical examinations of the dependence of edge effects on the optical density, which influence directly the contour sharpness in the image, are presented. Besides, the results of calculations of the influence of contrast in the characteristic curve of the radiation sensitive layer on the shape and properties of the limiting curve are shown. The results obtained are presented in the form of functions of changes in the relative edge enhancement indicator and maximum gradient of the limiting curve as dependent on the level and difference of the optical density in the image and background, respectively.
