Abstract
A magnetism measuring device includes a light source unit, a diamond crystal and an image sensor. The light source unit irradiates the diamond crystal with an excitation light, and irradiates the image sensor with a fluorescent light generated by the diamond crystal. The diamond crystal includes a plurality of nitrogen-vacancy pairs. The image sensor detects an intensity of the fluorescent light, which is generated from the diamond crystal, by a plurality of pixels. The image sensor and the light source unit are disposed so as to be contained within a projection area of the diamond crystal.
