BEC quantum vortex gyro implementation method based on active control

Abstract

The invention relates to a method for realizing a BEC quantum vortex gyroscope based on active control. According to the motion law of Bose-Einstein condensed matter gas clusters in magneto-optical potential wells, and using magneto-optical potential wells to control the trapped vortex clusters, an active control-based BEC quantum vortex gyroscope is proposed. The method uses the magneto-optical potential well to generate and actively control the BEC vortex gas atomic group, so that when the platform rotates, the oscillation parameters and precession parameters of the vortex gas atomic group are detected in real time, and the potential well parameters are adjusted according to the detection information, so as to realize the detection of the vortex gas atomic group. The scissor oscillation and precession of the atomic group are controlled, and the attitude angular rate of the platform is solved through the potential well parameters. The method has ultra-high precision and sensitivity. The invention belongs to the technical field of new concept quantum gyroscope, and can be applied to the design and research of quantum vortex gyroscope based on gaseous BEC.

Description

technical field [0001] The invention relates to a BEC quantum vortex gyro realization method based on active control, which is suitable for the design and research of the new concept quantum vortex gyro based on gaseous BEC. technical background [0002] Since the French physicist Leon Foucault discovered and named the gyroscope in 1850, the gyroscope, as the main inertial navigation detection equipment, has been widely used in navigation, aviation, aerospace, missiles, automobiles and other fields. Traditional electromechanical gyroscopes, laser gyroscopes based on the sagnac effect, and fiber optic gyroscopes have contradictions between the improvement of accuracy and sensitivity and the miniaturization of volume, weight, and power consumption, and have entered the bottleneck of the development of accuracy and sensitivity. [0003] In recent years, the rapid development of quantum physics and low-temperature physics has brought about a revolutionary impact. A series of ult...

Problems solved by technology

However, the quantum vortex gyroscope based on gaseous BEC still needs to be developed.

[0005] At present, foreign research on quantum vortex gyroscopes based on gaseous BECs is still limited to the in-depth exploration of the precession mechanism of BEC vortex gas atomic clusters, and there are few studies on the realization methods of gyroscopes.

However, domestic research on quantum vortex gyroscopes based on gaseous BEC has just started and needs to be developed urgently.

For the implementation method of quantum vortex gyro based on gaseous BEC, due to the constraints of existing detection technology, it is difficult to directly detect its momentum moment, but it is easy to directly detect its angle
