| Abstract: | In this paper, we described the progress of cold atom gyroscope. We launched the atoms along the same trajectory accurately and the opposite direction by controlling the frequency of directed digital system circuit. Using stimulated Raman beams, we operated the cold atoms and realized the atom interferometer fringes. With this configuration, it will greatly eliminate the common mode noise caused by uncertainty factor, such as the phase of the Raman laser beams, the gravity acceleration. It will significantly improve the precision in our experiment. The atom gyroscope will give a new way for the inertial navigation technology in the future. |
