Abstract

We demonstrate a strontium thermal-beam atom interferometer gyroscope (AIG) on a rotation table using the $^{1} S_{0}$ - $^{3} P_{1}$ intercombination line, and we measure large rotation rates exceeding 6 rad/s. Our demonstration relies upon a transit-time-resonant phase-modulation technique for detecting the AIG phase, which rejects signal background and variations in fringe amplitude.
