| Popis: | Our cold-atom gyroscope is based on a four-pulse configuration with a very large Sagnac area. Its short-term stability is limited by aliasing effects of the inertial forces (acceleration and rotation). We will show how continuous measurements and real-time compensation of the vibration during the interferometer sequence overcome this limit. |
