Latest Patents

Ravi is credited with 1 patent: “Solid-state spin sensor with a compliant head.” The invention describes a sensor system with a color-center ensemble in a solid-state substrate, used to detect magnetic fields. Its sensor head is compliantly coupled, allowing translational and rotational movement to accommodate different sample surfaces.

The system combines optical microscopy and optical driving to view and spin-polarize the color centers. A magnetic-field generator provides biasing, while microwave driving induces spin transitions. Force or image data can guide actuation to position the sensor precisely against a sample. By analyzing fluorescence data, the system produces a spatially resolved magnetic-field map. The patent also describes measurement methods using fiducials and force feedback, supporting wide-field quantum sensing on irregular surfaces.
