1. A device comprising:
- a diamond assembly including a diamond with one or more nitrogen vacancies;
a light emitting diode configured to emit light toward the diamond;
a first photo sensor configured to sense a first portion of the light emitted by the light emitting diode, wherein the first portion of the light does not travel through the diamond;
a second photo sensor configured to sense a second portion of the light emitted by the light emitting diode, wherein the second portion of the light travels through the diamond; and
a processor operatively coupled to the first photo sensor and a second photo sensor, wherein the processor is configured to;
compare a first signal received from the first photo sensor with a second signal received from the second photo sensor; and
determine, based on the comparison of the first signal and the second signal, a strength of a magnetic field applied to the diamond.

Abstract
A device includes a diamond with one or more nitrogen vacancies, a light emitting diode configured to emit light that travels through the diamond, and a photo sensor configured to sense the light. The device also includes a processor operatively coupled to the photo sensor. The processor is configured to determine, based on the light sensed by the photo sensor, a magnetic field applied to the diamond.

11. A method comprising:
-
emitting light from a light emitting diode; sensing, at a first sensor, a first light portion, the first light portion being a portion of the light emitted by the light emitting diode that has not traveled through a diamond with a nitrogen vacancy; sensing, at a second sensor, a second light portion, the second light portion being a portion of the light emitted by the light emitting diode that has traveled through the diamond with the nitrogen vacancy; and comparing the first light portion to the second light portion to determine a strength of a magnetic field applied to the diamond. - View Dependent Claims (12, 13)
