wave particle vortex gyroscope

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 applicable to the field of quantum navigation of a new generation, and can not only effectively improve the precision and sensitivity of the quantum gyroscope, but also realize small volume. technical background [0002] As an autonomous navigation system, the inertial navigation system has the advantages of all-weather, full-time and space-time, good concealment, not easy to be interfered, unable to be reversed and strong survivability compared with the satellite navigation system, but as a dead reckoning navigation system , the gyroscope error will cause its navigation parameter error to accumulate rapidly with time, that is, the navigation accuracy diverges with time, and the long-term stability is poor. Therefore, the gyroscope is the core of the inertial navigation system and the main bottleneck restricting the accuracy of inertial navigation. In response to the needs of future s...
