The Precision Radiometry for Incoherent Spectral Measurements (PRISM) Multidisciplinary University Research Initiative (MURI) Program is supported by the Air Force Office of Scientific Research (AFOSR) and Office of Naval Research (ONR).

This MURI will leverage our team’s interdisciplinary expertise in optical metrology, nanophotonics, astronomy, and quantum photonics to expand the fundamental limits of heterodyne spectroscopy. Using frequency combs, broadband light sources whose lines are phase-coherent, we will develop new schemes for measuring the spectra of incoherent sources with unprecedented bandwidth, frequency resolution, and spatial resolution. Blending the power of laser heterodyne radiometry with frequency comb techniques will significantly enhance the measurement of incoherent light sources and will enable a new level of precision in science, technology, and defense.
