The New Cryogenic Superfluid Gyroscope Based On Matter Wave Interference Effects

摘要

In this paper, the physical mechanism of the cryogenic superfluid gyroscope based on AC Josephson effect are analyzed, meanwhile, the implementation of the cryogenic superfluid gyroscope was brought up and the advantage of the sensitivity of the gyroscope is proved by theoretical derivation. A method to expand the measurement range based on amplitude locking technology are proposed, according to the problems of the insufficient range existing in the implementation of the cryogenic superfluid gyroscope based on AC Josephson effect when the information of corresponding angular velocity is extracted. Achievements of the study will be valuable reference to the simulation of cryogenic superfluid gyroscope.
