A STUDY OF SLIT DETECTION BY RADIOGRAPHY,
Abstract
Slit detection by radiography is dependent upon image contrast, dimensions of the slit and unsharpness. Experiments show that the contrast reduction factor for narrow slits is not a linear relation with unsharpness. Thus the equations based upon theory are valid for slit widths either several times smaller or larger than the unsharpness. For conditions where the unsharpness and slit width are of the same order of magnitude, an empirical formula must be used. (Author)
