Synthesis of exciting fields of eddy-current transducers for inspecting locally heterogeneous components and media : Soviet journal of nondestructive testing, Vol. 24, No. 5, pp. 337–344 (Jan. 1989)

Abstract

The author examines the problem of synthesis of two-dimensional exciting fields of eddy-current transducers designed for inspecting locally heterogeneous components and media and for detecting inclusions and metallic objects. The synthesis equations were derived and examined. The solution of these equations makes it possible to determine the spatial structure of the exciting magnetic field on the basis of the given output characteristics of the transducer from the coordinate of the local heterogeneities or surface defects in inspected components.
