The thin layer of homogeneously oriented nematic liquid crystal (NLC) applied on the optical quality solid crystal surface as a free film may visualize the images of structural defects through a polarizing microscope. On this basis a new non destructive method to study surfaces of different materials has been developed. A new application area of the NLC technique for investigation of structural inhomogeneities in solid crystals is discussed.
