Abstract
An optically pumped magnetometer device includes a first vapor cell having a light input window; a first light source configured to produce a first light beam; a first prism optic configured to receive the first light beam from the first light source and redirect the first light beam into the first vapor cell at a non-normal direction relative to the light input window of the first vapor cell; and a first light detector configured to receive the first light beam after passing through the first vapor cell. The device may also include additional light sources and light detectors which may share the prism optic and vapor cell (or utilize another prism optic or vapor cell or both).
