1. A magnetic measurement apparatus comprising:
- a diamond crystal having a plurality of nitrogen-vacancy pairs; and
an image sensor configured to detect a fluorescence intensity generated by an exciting light applied to the diamond crystal by using a plurality of pixels,wherein the nitrogen-vacancy pairs of the diamond crystal are made to one-to-one correspond to the pixels, and fluorescence generated by one of the nitrogen-vacancy pairs is received by one of the pixels made to correspond to the nitrogen-vacancy pair.

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.
