| 摘要 |
The invention relates to a method for manufacturing an inspection head (10) for non-destructive eddy current inspection, which comprises the following steps: optimising (102) a geometric configuration (Pi, Pt) of at least one coil (E, R) of the inspection head (10) and manufacturing (106) the inspection head (10) in accordance with the geometric configuration (Pi, Pt) of said at least one coil (E, R) performing said optimisation (102). The optimisation (102) of the geometric configuration (Pi, Pt) of said at least one coil (E, R) is performed according to a criterion (C1) for optimising the observance of a ratio of proportionality between a variation of the imaginary portion of a complex electric quantity induced in at least one coil with a receiving function (R) and a variation of the real portion of said complex electrical quantity, when said variations are due to a variation in the electrical conductivity and/or magnetic permeability of a part to be inspected. |
