Fluorescenční mikroskopie a analýza obrazu mikroporušení hornin
Ščučka, Jiří ; Kožušníková, Alena ; Obara, B.
The paper presents analytical methods used at the Institute of Geonics ASCR for quantitative analyses of micro-fracturing arising in rocks under various loading conditions in laboratory. Primarily optical fluorescence microscopy and image analysis of sections saturated by fluorescence dye are used to these purposes. The full-automatic image analysis method for determination of intensity and distribution of micro-cracks in rock specimens is presented in the paper as well as the formerly used manually procedure.
