Automatic Image Processing System for Nuclear Film Detectors

Abstract

<p>A system to process automatically nuclear film detectors was developed by interfacing a commercial television camera to a computer and analyzing the two level images of white objects on a dark background.</p> <p>Two analysis methods were used; it is concluded that they have different ranges of application. For intermediate to high fluencies (> 100 impacts/mm²) the antitransformation of the white line length distribution function obtained throughout a raster scan provides results with uncertainties smaller than the statistical fluctuations of the hole density in the film. For fluencies down to 20 impacts/mm² a direct image analysis gives more accurate results in reasonably short times. The limiting factor for very low fluencies is the resolution of the television camera.</p>
