Аннотация:
The thin layer of homogeneously oriented nematic liquid crystal (NLC) applied on an optical polished glass surface as a free film may visualise through a polarising microscope cleaning defects, local physical and chemical modifications of the surface and local relief defects. On this basis a new method to study different types of polished surfaces has been developed. The first results obtained are described.
