Patent Description The new NIST detector senses very small phase shifts in a highly balanced microwave bridge. An electric field optimized microwave probe, in close proximity to a sample, serves to perturb the degree of bridge balance due to a change in effective dielectric constant of the sample
Patent Description This invention provides for a new and useful metrology to enable counterfeit detection system capable of uniquely marking items by encoding information in their physical structure at the nanoscale. The system depends on rapidly encoding information in the physical structure of an
NMR endures as one of the most powerful analytical tools for detecting chemical species and elucidating molecular structure. Zero-to-ultralow-field NMR spectroscopy is a new, potentially portable and cost-effective modality to determine the molecular structure and properties of microfluidic chemical samples.
This technology is a device that integrates a microfluidic channel and an alkali vapor cell on a microchip-like platform. In conjunction with a near resonant laser beam, the alkali vapor cell forms the basis for an atomic magnetometer, competing with (or even exceeding) the sensitivity of magnetometers based on SQUIDs.
Gyroscopes sense rotation. In combination with magnetometers, gyroscopes are used many applications. The NIST invention enables multitasking measurement capabilities and is the first to demonstrate simultaneous measurement of rotation, rotation angle and acceleration with a single source of atoms.
Measurement of faint magnetic fields is critical to many applications, including medical diagnostics, but conventional technologies are often large, complex and expensive. NIST’s chip-scale atomic magnetometer is highly compact and readily fabricated using familiar semiconductor techniques.
