【 摘 要 】

This paper presents the methodogical approach to the assessment of geometrical and localization parameters for crack-type defects (including hidden subsurface flaws) by means mathematical treatment of experimental information represented by the amplitude displacement fields of researchable object registered by optic-interference methods.
