Abstract
High-accuracy magnetic measurement is performed by efficiently using nitrogen-vacancy pairs in all orientations. A magnetic measurement apparatus includes a diamond crystal and an image sensor. The diamond crystal has nitrogen-vacancy pairs. The image sensor detects the intensities of fluorescence generated by an exciting light applied to the diamond crystal by using a plurality of pixels. The nitrogen-vacancy pairs of the diamond crystal are made to one-to-one correspond to the pixels. The fluorescence generated by one nitrogen-vacancy pair is received by one pixel made to correspond to the nitrogen-vacancy pair.
