Abstract

The invention relates to an automatic data acquisition and analysis system of a cold atom interferometer. The system comprises time sequence control system hardware, a computer and a network communication interface, and the time sequence control system hardware is used for controlling a magneto-optical trap to capture or enable an atomic group to act, Raman laser to act on the atomic group and atomic detection optical signal data transmission; the computer is used for operating time sequence control system software, controlling time sequence control system hardware to carry out a cold atom interference experiment and analyzing an atom detection optical signal; and the network communication interface is used for connecting a computer and time sequence control system hardware. Time sequence control hardware of a cold atom experiment and interference fringe real-time analysis are integrated together, the experiment time sequence can be adjusted, interference fringe data corresponding to each experiment can be simply and conveniently obtained, and the automation degree of the cold atom interference experiment is greatly improved; and time loss caused by switching of different software and movement of experimental data in the experimental process is eliminated.

Description

technical field [0001] The invention relates to the technical field of data collection and analysis, in particular to an automatic data collection and analysis system of a cold atom interferometer. Background technique [0002] The cold atom interferometer uses three beams of Raman light to change the internal state of the atomic cluster to complete the interference process. Constantly changing the phase of the third beam of Raman light can create a phase difference between it and the second beam of Raman light, and obtain the interference fringes required for measurement. The detection light signal after cold atom interference is collected by a high-speed photodetector, and the transition probability is calculated from the amplitude of the detection light, and then a complete interference fringe is obtained. [0003] Data collection involves the detection of light electrical signals that are captured by an analog-to-digital converter and processed in the form of voltage da...
