Circuit board integrated atomic magnetometer and gyroscope

摘要

Magnetometers, atomic sensors and related systems, methods and devices are disclosed. In one configuration, an assembly for use in a high-sensitivity atomic sensor can include an alkali vapor cell, at least one illumination source configured to emit light when activated, the emitted light having a first predetermined range of wavelengths, a light collector capable of collecting light in the first predetermined range of wavelengths, and a plurality of optical elements arranged such that (a) light emitted from the at least one illumination source is directed to the alkali vapor cell, and (b) light emerging from the alkali vapor cell is directed to the light collector.

1. An assembly for use in a high-sensitivity atomic sensor, the assembly comprising:
an alkali vapor cell; at least one illumination source configured to emit light when activated, the emitted light having a first predetermined range of wavelengths; a light collector capable of collecting light in the first predetermined range of wavelengths; a plurality of optical elements arranged such that (a) light emitted from the at least one illumination source is directed to the alkali vapor cell, and (b) light emerging from the alkali vapor cell is directed to the light collector; a generally planar electrical insulator having a top and a bottom, the top and the bottom being opposed to one another, wherein at least one of the alkali vapor cell, illumination source, or an optical element is supported upon the generally planar electrical insulator; a top trace on the top of the insulator; a bottom trace on the bottom of the insulator; and a through trace, the insulator defining a via from the top to the bottom, the through trace contacting both the top trace and the bottom trace and passing through the via so that the top trace, bottom trace and through trace form a single electrically conductive element; wherein the top trace and the bottom trace are congruent so that a current along the single electrically conductive element tends to create a self-cancelling magnetic field.
