An integrated system of coherent layout trapped atomic clock and nuclear magnetic resonance atomic gyroscope

Abstract

The invention discloses a coherent layout confinement atomic clock and nuclear magnetic resonance atomic gyroscope integrated system which comprises a three-axis coil, an atomic bubble arranged in the three-axis coil, a signal generator connected with the three-axis coil, a detection light arranged outside the three-axis coil and used for a nuclear magnetic resonance atomic gyroscope, a pumping light used for the nuclear magnetic resonance atomic gyroscope and a chip atomic clock, a second photoelectric detector used for detecting a light inspection signal of the nuclear magnetic resonance atomic gyroscope, and a first photoelectric detector used for detecting a CPT resonance signal of the chip atomic clock, wherein the detecting light is orthogonal to the pumping light, and a first frequency-stabilizing servo loop and a second frequency-stabilizing servo loop are connected between the first photoelectric detector and the pumping light. The coherent layout confinement atomic clock and nuclear magnetic resonance atomic gyroscope integrated system has a great significance for shortening volume, power consumption and weight of a Micro-PNT, is beneficial to improvement of the performance of the chip atomic clock, and is high in practical value.

Description

technical field [0001] The invention relates to an integrated system of a coherent layout trapped atomic clock and a nuclear magnetic resonance atomic gyroscope, belonging to the field of atomic clocks and nuclear magnetic resonance atomic gyroscopes. Background technique [0002] With the development of science and technology, navigation and positioning systems have been used more and more in military and civilian applications, but there are still some problems. Satellite navigation has the characteristics of small size and low cost, but its anti-interference ability is insufficient, and it is easy to be shielded or blocked; inertial navigation has strong anti-interference ability, but it has shortcomings such as large volume and weight, slow warm-up and start-up, high cost, and no time information. In order to meet the needs of precise strikes, rapid response, coordinated operations, and autonomous survival proposed by modern warfare, it is imperative to study a navigation...
