PALACIOS, D; PALACIOS, F  e  VILORIA, T. Quantification and differentiation of nuclear tracks in solid state detectors by simulation of their diffraction pattern applying Fourier optics. Rev. mex. fis. [online]. 2006, vol.52, suppl.3, pp.214-216. ISSN 0035-001X.

The proposed method to count and differentiate nuclear tracks in Solid State Detectors is based on digital simulation and analysis of the Fraunhofer diffraction pattern, formed when coherent light passes through tracks in an etched detector. Analytical and numerical models were developed using, as transformation element, an optical system and a digital procedure of the Fourier Transform, respectively. Different components of developed software are described, and depending on the kind of detector used, variants of optical microscopy are suggested. The proposed method allows to calculate real track density and to differentiate tracks by their diameters.
