MAGNETIC MEASURING DEVICE
First Claim
1. A magnetic measuring device for detecting a magnetic field intensity from a change of a fluorescent light intensity, comprising:
- a diamond crystal having a plurality of nitrogen-vacancy pairs;
a microwave unit irradiating the diamond crystal with a microwave;
a light source unit irradiating the diamond crystal with excitation light;
an image sensor detecting a fluorescent light intensity generated from the diamond crystal by a plurality of pixels;
a signal processing unit performing image processing of a fluorescent image taken-in by the image sensor; and
a control unit controlling an operation of the light source unit, the microwave unit, and the signal processing unit,wherein the light source unit is provided on a first surface side of the diamond crystal, andthe image sensor is provided on a second surface side opposed to the first surface of the diamond crystal.

Abstract
A magnetic measuring device can be downsized. The magnetic measuring device includes a diamond crystal, a microwave source, a light source array/microwave circuit chip, an image sensor, and a signal controller. The diamond crystal contains a plurality of nitrogen-vacancy pairs. The microwave source generates the microwave that is irradiated to the diamond crystal. The microwave circuit unit in the light source array/microwave circuit chip irradiates the diamond crystal with the microwave. The light source array in the light source array/microwave circuit chip irradiates the diamond crystal with excitation light. The image sensor detects an intensity of fluorescent light generated from the diamond crystal. The signal controller performs image processing of a fluorescent image taken-in by the image sensor, and controls operations of the light source array/microwave circuit chip and the microwave source. The light source array/microwave circuit chip is provided on a first surface side of the diamond crystal, and the image sensor is provided on a second surface side opposed to the first surface of the diamond crystal.
