Abstract: According to some aspects of the present disclosure, an atomic clock and methods of forming and/or using an atomic clock are disclosed. In one embodiment, an atomic clock includes: a light source configured to illuminate a resonance vapor cell; a narrowband optical filter disposed between the light source and the resonance vapor cell and arranged such that light emitted from the light source passes through the narrowband optical filter and illuminates the resonance vapor cell. The resonance vapor cell is configured to emit a signal corresponding to a hyperfine transition frequency in response to illumination from the light source, and a filter cell is disposed between the light source and the resonance vapor cell and configured to generate optical pumping. An optical detector is configured to detect the emitted signal corresponding to the hyperfine transition frequency.

CPC classification number: G01R33/26 , G01R33/246
Abstract: A magnetographic camera may be based on an optically pumped magnetometer (OPM). The magnetographic camera may measure a spatial distribution of magnetic field produced by a sample that may be stationary in time or may dynamically vary with time. The magnetographic camera may include a magnetic field detector housing containing a vapor cell. The magnetographic camera may include a laser light source to illuminate the vapor cell causing a magnetic field image of a sample to be generated. The magnetographic camera may include an optical detector to encode and store the magnetic field image of the sample that is spatially encoded as a distribution of light.

Abstract: Various embodiments of the present technology relate generally to the field of imaging the spatial distribution of magnetic field of biologic and non-biologic materials that may change over time and more particularly to the apparatus and methods for making such a static or dynamic spatial imaging of magnetic field distributions. Some embodiments provide for apparatus and methods for a novel magnetographic camera which enables a unique ability to determine the spatial distribution of magnetic field in a biological or non-biological sample with high spatial and temporal resolutions and high sensitivity. The use of these embodiments will greatly expand the applications of OPM-based cameras in medicine, science and industry.
