摘要

The article discusses the principles of the Schlieren optical visualization method as applied to an evaluation of the properties of optically transparent materials, especially transparent polymeric foils. The quality of images is a very important factor during visual evaluation, especially when to use quantitative in methods in the description of images of foils. One of the ways to affect the subsequent quality of an image achieved by visualization methods is the correction of the inhomogeneous brightness of the image, the sharpening of images and the adjustment of the Schlieren optical apparatus. In this way we can acquire images that are suitable for the identification, comparison and defectoscopy of transparent polymeric foils.
