Abstract
An array of optically pumped magnetometers includes an array of vapor cells; and an array of beam splitters. The array of beam splitters is arranged into columns, including a first column, and rows. Each row and each column includes at least two of the beam splitters. The array of beam splitters is configured to receive light into the first column of the array and to distribute that light from the first column into each of the rows and to distribute the light from each of the rows into a plurality of individual light beams directed toward the vapor cells.

An array of optically pumped magnetometers, comprising:
- an array of vapor cells;
- and
- an array of beam splitters, wherein the array of beam splitters is arranged into a plurality of columns, including a first column, and a plurality of rows, wherein each row and each column comprises at least two of the beam splitters, wherein the array of beam splitters is configured to receive light into the first column of the array and to distribute that light from the first column into each of the plurality of rows and to distribute the light from each of the rows into a plurality of individual light beams directed toward the vapor cells, wherein the beam splitters are bonded together into a single block using optical adhesive.
An array of optically pumped magnetometers, comprising:
- an array of vapor cells;
- and
- an array of polarizing beam splitters, wherein the array of polarizing beam splitters is arranged into a plurality of columns, including a first column, and a plurality of rows, wherein each row and each column comprises at least two of the polarizing beam splitters, wherein the array of polarizing beam splitters is configured to receive light into the first column of the array and to distribute that light from the first column into each of the plurality of rows and to distribute the light from each of the rows into a plurality of individual light beams directed toward the vapor cells.
A magnetic field measurement system, comprising:
- an array of vapor cells;
- an array of light detectors configured to receive light passing through the vapor cells;
- an array of beam splitters, wherein the array of beam splitters is arranged into a plurality of columns, including a first column, and a plurality of rows, wherein each row and each column comprises at least two of the beam splitters, wherein the array of beam splitters is configured to receive light into the first column of the array and to distribute that light from the first column into each of the plurality of rows and to distribute the light from each of the rows into a plurality of individual light beams directed toward the vapor cells;
- and
- a wearable article within which the array of vapor cells, array of light detectors and array of beam splitters are disposed.
