The NIST on a Chip project in the Atomic Devices and Instrumentation group is focused on the development of compact, manufacturable, low power, SI-traceable calibration instruments using atomic vapor cells. We anticipate such devices could be broadly used in industrial settings for in-situ calibration of instruments and systems. This technology is inspired by past work on chip-scale atomic clocks, which were invented at NIST and have been successfully commercialized. Specifically we are developing:
- Length standards based on precision optical spectroscopy of atomic vapors confined in a cell
- Time standards based on miniaturized cold atom technology
- Current standards based on accurate magnetometry
- Temperature standards using Doppler thermometry
