The invention relates to the technical field of atomic energy level transition detection, and discloses a method for reducing an atomic energy level transition dynamic detection frequency range of an atomic clock. The method comprises the steps that deviation correcting voltage is sent to a signal generator, reference voltage is sent to a voltage control crystal oscillator, the signal generator outputs a signal to an integrated module of the atomic clock, the voltage control crystal oscillator outputs a signal to a microwave multiplying mixing module of the atomic clock, and atomic clock general loop closing working is conducted.

technical field [0001] The invention relates to the technical field of atomic energy level transition detection, and is mainly applicable to a method for narrowing the dynamic detection frequency range of atomic energy level transition of an atomic clock. Background technique [0002] In the practical application of the atomic clock, the voltage-controlled crystal oscillator outputs the signal to the synthesis module and the microwave frequency mixing module; the synthesis module adds a small frequency modulation to the received signal, and then outputs the microwave modulation signal to the microwave frequency mixing module and the microwave frequency mixing module. Servo module; the microwave multiplication and mixing module first multiplies the output signal of the voltage-controlled crystal oscillator, and then mixes the multiplied signal with the microwave modulation signal output by the integrated module to generate a microwave detection signal, and then converts the mi...

Problems solved by technology

[0004] However, the frequency range of the current dynamic detection of atomic energy level transitions is relatively large, so the accuracy of the dynamic detection of atomic energy level transitions of the entire atomic clock is low, thereby reducing the use efficiency of the atomic clock

This will have an impact on some special applications of atomic clocks, such as large errors in precise guidance and timing
