THE NEMATIC LIQUID CRYSTALS APPLICATION TO QUARTZ RESONATORS STRUCTURAL DEFECTS DETECTING
Annotation
The nematic liquid crystals (NLCs) application to quartz resonators structural defects detecting at industrial conditions is described. Natural and artificial quartz structural heterogeneities appearing at technological processing were the subject of investigation. NLCs technique was compared with etching, x-ray and acoustic methods. It was demonstrated that suggested NLC technique is non-destructive in comparison with etching; more accurate in comparison with acoustic method, and as opposed to it, gives the possibility of integrated picture of examined surface parameters; and more expressive and cheep in comparison with x-ray method. NLC technique can be considered as an independent method that gives additional information about the characteristics of objects under investigation.
