Crack inspection is a critical issue in quantitative nondestructive evaluation (NDE). The eddy current (EC) method is effective for surface discontinuities detection, but the spatial resolution of conventional EC method is constrained by the size of EC probe. The photoinductive (PI) imaging method is a NDE technique that combines EC and laser-based thermal(More)
This paper presents an analysis method that combines the nondestructive resonant electromagnetic testing and the mathematical model for determining the thickness and conductivity of molybdenum (Mo) thin layer in copper indium gallium selenide (CIGS) solar cells. This technique is demonstrated for Mo layers (0.5–1.5 m) over glass substrate. The impedance of(More)
