OPTICAL METHODS FOR EXAMINING AND COMPARING OPTICALLY TRANSPARENT POLYMER FOILS

Lívia Syrová

   The contribution treats the topic of acquiring information on the properties of optically transparent materials by the Schlieren method applied under laboratory conditions, and on processing the experimentally gained information by means of a special computer code based on a reference image. Experimental results obtained on various objects of observation, such as polymer foils, and their graphical and numerical interpretation are presented as well.

Keywords: optical visualisation, Schlieren method, polymeric foils, picture pre-processing
