Research Progress of Cold Atom Interferometer Gyroscope

In recent years, the technique of cold atom interference based on laser cooling and trapping has been developed rapidly, which provides a new research direction for precise rotation measurement. Compared with the traditional gyroscope, cold atom interference gyroscope has higher sensitivity and is a new generation of inertial measurement instrument. Based on the measurement principle of cold atom interference gyroscope, the implementation scheme and research status of cold atom interference gyroscope at home and abroad in recent years are introduced in this paper, and the advantages and disadvantages of each scheme are also compared. Finally, the overall technical scheme of developing cold atom interference gyroscope is proposed, which provides a technical basis for the development of gyroscope prototype with high precision and dynamic measurement.
