Compact atom interferometer integration device

The invention discloses a compact atom interferometer integration device which comprises a cold atom interferometer physical system, a cooling optical module, a Raman optical module, a fluorescence detection and collection device and the like. The structure of a single decahedral vacuum glass cavity is utilized, and a collimation beam expander, a magnetic field coil and the like are effectively integrated. According to the decahedral vacuum glass cavity, the defects of induced current, induced magnetic field and the like of a metal vacuum cavity are overcome, the light transmission area is larger, and the size is smaller. The cooling optical module and the Raman optical module are simpler than an existing optical system for realizing atom interference, the optical path structure is simplified, and the optical path cost is reduced. The cube vacuum cavity of the device and peripheral devices are mutually independent, the cooling optical module and the Raman optical module can be independently debugged and then
