TY - JOUR ID - 209091 AU - Ohlídal, Miloslav - Vrána, Josef - Michálek, Aleš - Pražák, Dominik - Jákl, Miloš - Ohlídal, Ivan PY - 1999 TI - New Ways od Observing Optical Inhomogeneities in Glass PB - The Czech Glass Society CY - Prague, Czech Republic SN - 802383861x KW - optics KW - spatial filtering KW - phase-objects KW - optical inhomogeneities N2 - A method allowing us to visualise optical inhomogeneities in glass products (phase-objects) is presented. The method is based on spatial filtering the image of the products, combined with recording the image by means of a CCD camera, digitising and computer processing this image. This method allows us to evaluate sensitively, automatically and objectively the stucture and the concentration of those inhomogeneities. Selected results are illustrated. ER -
