Detection method of integrated machine performance suitable for atomic clock

Abstract

The invention relates to the technical field of detection methods, and discloses a detection method of integrated machine performance suitable for an atomic clock. The detection method of the integrated machine performance suitable for the atomic clock comprises steps as below: firstly carrying out feedback of the original signals outputted by a signal source through signals generated by microwave processing and a physical system of an atomic clock. At the same time, a voltage-controlled oscillator is used as an external time base reference source of the signal source; directly obtaining the signals of the signal source through the feedback and carrying out analyzing and detecting of the signals of the signal source. The detection method of the integrated machine performance suitable for the atomic clock carries out accurate detection of the integrated performance of the atomic clock on the basis that long-period stable working of the atomic clock is not affected.

Description

technical field [0001] The invention relates to the technical field of detection methods, and is mainly applicable to the detection method of the overall performance of an atomic clock. Background technique [0002] The optically pumped rubidium atomic frequency standard is a traditional practical atomic frequency standard. Although some performance indicators are not as good as cesium and hydrogen atomic frequency standards, it is the most widely used and cheapest atomic frequency standard. Its accuracy is l0 -11 , the stability is 10 -12 order of magnitude. Miniaturization is the development trend of optically pumped rubidium atomic frequency standards. At present, many domestic units are actively carrying out miniaturization work in the field of rubidium atomic frequency standards. The miniaturization of rubidium atomic frequency standards in the world has also made rapid progress, and rubidium atomic frequency standards on the order of decimeters have been commerciali...

Problems solved by technology

[0016] The efforts made by many researchers in the above-mentioned aspects are to further improve the overall performance of the atomic clock. If you really want to improve the performance of the atomic clock system, you can only start with its physical system. But for a specific atomic clock, once it is integrated The physical system is fixed, and all its properties can only be obtained indirectly by the influence of physical effects in the long-term working process, and some influences have brought a lot of trouble to the long-term stable work and accuracy of the atomic clock.
