Embodiment Construction

[0038] Specific implementation plan

[0039] The present invention is a wave-particle vortex gyroscope, and its principle scheme is as follows Figure 4 As shown, the specific implementation steps are as follows:

[0040] (1) Use laser and spiral phase plate to build vortex optical quantum interference device

[0041] Use a laser to generate a standard Gaussian distribution laser beam (such as figure 1 As shown), and then according to the Laguerre-Gaussian beam (LG beam for short) wave function expression factor to determine the phase information of the vortex light to be generated. The incident light is incident on the spiral phase plate at a certain angle to adjust the coherence of the beam, and the required vortex light with high-order orbital angular momentum can be obtained, such as figure 2 As shown; according to the principle of rotating Doppler, it can be seen that the rotation of the light source will cause the angular frequency of the vortex light beam to shift in two aspe...

Abstract

The invention relates to a wave particle vortex gyro. Vortex light is used for producing a room temperature Bose-Einstein condensation (BEC) vortex superposition state, to-be-measured information carried by the vortex light orbital angular momentum is transmitted to room temperature BEC; a room temperature BEC vortex-state matter wave in a quantum well can generate an interference phenomenon along with rotation of a platform; phase position changes are detected through a detection system, and the to-be-measured information can be obtained. Through the cascade vortex light and the room temperature BEC, high-precision sensitivity of the matter wave is used for achieving surging amplification of vortex light inertial measurement sensitivity, so as to achieve ultra-high precision and ultra-high sensitivity measurement of the attitude angular rate. Compared with an atomic gyro based on ultra-low temperature BEC, because the vortex superposition state of the room temperature BEC is quite stable and the vortex light and the vortex matter wave can form light paths by self, the vortex light and the room temperature BEC cascade surging can achieve high stability and miniaturization of the gyro. The wave particle vortex gyro belongs to the inertial measurement technical field, and can be applied in the fields of ultrahigh-sensitivity and miniaturized navigation positioning and the like in future.

Description

Technical field [0001] The invention relates to a wave-particle vortex gyroscope, which is suitable for the field of a new generation of quantum navigation, and can not only effectively improve the precision and sensitivity of the quantum gyroscope, but also can achieve a small volume. technical background [0002] As an autonomous navigation system, inertial navigation system has the advantages of all-weather, all-time and space, good concealment, not easy to be interfered, unable to be counter-utilized, and strong survivability compared with satellite navigation system, but as a predictive navigation system , Gyroscope error will cause its navigation parameter error to accumulate rapidly over time, that is, navigation accuracy diverges with time, and long-term stability is poor. Therefore, the gyroscope is the core of the inertial navigation system and the main bottleneck restricting the accuracy of the inertial navigation. In response to the needs of future aerospace activiti...
