| Abstract: | This paper presents the design and development of a two-dimensional eddy current sensor array and the improved response of the array using a super-resolution algorithm. A computational model of the array is derived using dyadic Green's function and volume integral method. This application was realized for detecting fatigue cracks, introduced in AISI 304 samples by subjecting them to cyclical loading. |
