Description

technical field [0001] The invention relates to a circulating water-cooled constant temperature device for miniaturized SERF gyroscopes, belonging to the application field of SERF gyroscopes. Background technique [0002] Under the conditions of high atomic density and zero magnetic environment, the electron spin of the SERF gyroscope enters the spin-exchange-free relaxation (SERF) state, and the magnetic moment of the electron spin has a fixed axis. The SERF gyroscope uses this feature to realize the carrier rotation information For measurement, the gyroscope has the characteristics of small size, ultra-high precision and dual-axis output. The stability of the SERF state directly determines the index performance of the SERF gyroscope. The temperature determines the density of the alkali metal atomic number of the SERF gyroscope, and it grows exponentially. The small fluctuation of the temperature directly causes a large change in the atomic number density, resulting in atom...
