[0067] specific implementation plan
[0068] The implementation object of the present invention is a vortex superposition gyroscope based on cold atom BEC, and the schematic diagram of the specific implementation is as follows figure 1 As shown, the specific implementation steps are as follows:
[0069] The vortex superposition gyroscope based on cold atom BEC (such as Figure 5 ) is to use the Sagnac effect of the vortex superposition matter wave to realize the sensitivity to the angular rate. Therefore, after generating a stable interference pattern, it is necessary to detect the phase information of the interference pattern to obtain the angular velocity of the system.
[0070] Through the transfer of orbital angular momentum of superposition vortex light, a stable vortex superposition state matter wave can be formed in the BEC, resulting in a stable standing wave. The standing wave is reflected in the density distribution of cold atoms, that is, the density distributio...
