First Claim
Patent Images
1. A device comprising:
- a diamond with a nitrogen vacancy;
a light source configured to transmit light toward the diamond;
a first sensor configured to sense a first portion of the light transmitted from the light source, wherein the first portion of the light does not travel through the diamond;
a second sensor configured to sense a second portion of the light transmitted from the light source, wherein the second portion of the light travels through the diamond;
a third sensor configured to sense a third portion of the light, wherein the third portion of the light travels through the diamond to the third sensor;
a first light pipe configured to direct the second portion of the light from the diamond to the second sensor;
a second light pipe configured to direct the third portion of the light from the diamond to the third sensor, wherein the first light pipe and the second light pipe are aligned along a central axis;
a first waveguide cutoff filter surrounding the first light pipe that is configured to attenuate electromagnetic waves; and
a second waveguide cutoff filter surrounding the second light pipe.

Abstract
A device includes a diamond assembly. The diamond assembly includes a diamond with a plurality of nitrogen vacancy centers and electrical components that emit electromagnetic waves. The device also includes a light source configured to emit light toward the diamond and a photo detector configured to detect light from the light source that traveled through the diamond. The device further includes an attenuator between the diamond assembly and the photo detector. The attenuator is configured to attenuate the electromagnetic waves emitted from the electrical components of the diamond assembly.
