QuSpin N1 Data Workflow: From Sensor to Source Localization

QuSpin’s optically pumped magnetometers (OPMs) have transformed non-invasive neuroimaging by enabling high-resolution, on-scalp measurements with flexible sensor arrays. But with flexibility comes complexity: determining the precise position and orientation of each sensor is critical for accurate source localization. To streamline this process, QuSpin developed a complete analysis pipeline that begins with the HALO system for… Read more »

Python based QuSpin Sensor Localization Software Release

5/20/2025 We’re excited to announce the beta release of QuSpin’s newly updated localization analysis software for the Neuro-1 system. This builds upon previous builds with upgrades that mark a major step forward in usability and automation. What used to require manual tuning is now streamlined—just load your data, select a few sensors, and hit “Go.”… Read more »

Robust, Lightweight Carbon Fiber Packaging for QTFM Gen-2

QTFM stands as one of the most sensitive and compact scalar atomic magnetometers available today. Many QTFM applications also need compact, robust, and lightweight packaging for deployment, especially on mobile platforms like UAVs (Unmanned Aerial Vehicles) and UUVs (Unmanned Underwater Vehicles). To meet these requirements, we have developed a carbon fiber-based solution (add-on) that simplifies… Read more »

New Triaxial QZFM

Our current Gen-2 QZFM can sense y and z components of the magnetic field but not x. Because many applications can greatly benefit from a sensor that can detect all three components, we have developed a new triaxial variant. The triaxial variant has the same size, weight, power, and cost as the standard variant. The… Read more »
