Applied Physics Division

Our mission is to advance measurement science & technology in areas of critical importance to national priority needs, such as, advanced manufacturing, national security, quantum communications, strategic computing, and quantitative imaging. Photonics, magnetics, and imaging are transformative technologies where fundamental metrological basis is needed to address these national priority needs.

The Division's key competencies include radiometry, advanced communications, sensing, quantum measurements, quantitative imaging, spectroscopy, and laser safety. In addition, the Division operates a state-of-the-art precision imaging facility to characterize unique devices that improve measurement science, standards, and services. Division staff include world experts in laser metrology, quantum metrology, quantitative imaging, as well as photonic and magnetic applications. The Division's focus on a targeted set of technical challenges enables us to maximize impact and benefit from collaborations with industry, government, and university stakeholders.
