|発明の名称||MAGNETIC MEASURING DEVICE|
PROBLEM TO BE SOLVED: To provide a magnetic measuring device capable of measuring magnetism with high sensitivity even if a diamond board is not highly pure and density and electron spin coherence time of an NV center are nonuniform.
SOLUTION: A magnetic measuring device includes: a determination part for identifying four maximum inclination points in an average value within a visual field of a light detection magnetic resonance spectrum and determining a degree of decrease in relative fluorescence intensity and microwave frequencies in the respective maximum inclination points; a setting part for setting a reference decrease degree of relative fluorescence intensity in a predetermined area and setting operating point frequency initial values of four points for achieving a reference decrease degree near microwave frequencies in the maximum inclination points; a frequency update part for updating operating point frequencies in four points; a frequency correction part for inputting the updated operating point frequencies to a microwaves oscillator as corrected operating point frequencies; and an integration part for integrating detection results of an image sensor in each of the corrected operating point frequencies for each pixel.
