Adalidi U. Magneto-optical visualization of magnetograms of relief images and structural heterogeneities in of ferromagnetic productions superficial layer

The dissertation is dedicated to improve efficiency of non-destructive checking of relief and structural heterogeneities in superficial layer of ferromagnetic productions. This solution is based on the creation and application of a new magneto-optical visualization method. It is used for visualization of magnetograms, which allows non-destructive investigation of relief and structural heterogeneity in superficial layers of ferromagnetic productions. The theoretical basis is proposed and validated for new method to magnetization (local polar magnetizing), which support selective stimulation of the magnetic fields dispersion in superficial layers and record magnetic copy with magnetic biasing. For the first time there are developed main principles of magneto-optical visualization of lengthy objects. Theoretical amplitude-frequency response of record and visualization route is built. Also there are proposed and tested algorithms for automatic image correction which arise
