Document Type and Number:
Japanese Patent JP6792859
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an analysis method, an analysis program and an analyzer which enable characteristics of an analysis object to be easily and accurately analyzed.SOLUTION: The analysis method is provided that comprises: exciting an analysis object by applying an AC electric signal at a first frequency to a first coil to generate a first eddy current in the analysis object; measuring a first electric state quantity corresponding to a voltage generated in a second coil by a magnetic field formed due to the first eddy current; exciting the analysis object by applying an AC electric signal at a second frequency to the first coil to generate a second eddy current in the analysis object; measuring a second electric state quantity corresponding to a voltage generated in the second coil by a magnetic field formed due to the second eddy current; and analyzing thickness-direction characteristics of the analysis object on the basis of the first electric state quantity and the second electric state quantity.SELECTED DRAWING: Figure 10
