Abstract

V originále

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.
