Embodiment Construction

[0032] Specific technical solutions of the present invention will be described in connection with examples.

[0033] like figure 1 As shown, 852 nm laser as a detective light 1,1470 nm laser as a modified light 2, 779 nm laser as a coupling light 3, and the three beam light excited in the atoms in the contained glass bubble 4, and finally realizes the four-level Ride Fort electromagnetic induction transparent. The trimming light 2, the coupling light 3 is bundled by the second dichroic mirror 8, reflected by the third two-chromosome 7, into the cerium glass bubble 4; detecting light 1 is divided into two bouques Through the first dichroic mirror 6, one beam detecting light 1 is coincided with the modified light 2 in the contaminated glass bubble 4. The microwave frequency comb signal of the microwave frequency comb 13 is then loaded into the sensor-containing glass bubble 4 by the microwave symbol 12 into the speaker antenna 5 through the microwave syllable 12.

Abstract

The invention belongs to the technical field of microwave electric field sensors, and specifically relates to a Rydberg atomic microwave electric field sensor and detection method based on a microwave frequency comb, including three beams of light, probe light, modification light, and coupling light. The atoms in the cesium-containing glass bubble go to the Rydberg state; the cesium-containing glass bubble is equipped with a horn antenna, a microwave frequency comb, and a signal field to be measured, and the microwave frequency comb signal of the microwave frequency comb and the signal to be measured in the signal field to be measured pass through The microwave combiner enters the horn antenna and loads it on the cesium-containing glass bulb; it also includes a differential detector for reading the beat frequency signal; the differential detector is connected with the data processing system, and the data processing system analyzes the beat frequency signal. The present invention can break through the limitation of the instantaneous bandwidth of Rydberg atoms on the signal bandwidth that can be measured in real time, and uses two sets of microwave frequency combs with different frequency intervals to realize the frequency measurement of the microwave signal, avoiding the interference of the image frequency on the determined frequency.

Description

Technical field [0001] The present invention belongs to the technical field of microwave electric field sensors, and specific relates to a Microwave frequency combing Ridurg atomic microwave electric field sensor and detection method. Background technique [0002] The existing parallel detection scheme used in the experimental scheme based on the Ridurg Atom can be constructed in real time by the relaxation time limit of the atomic electromagnetic induction transparent phenomenon, which can detect the maximum bandwidth of about 10 MHz in real time, based on microwave frequency Comb Reed atomic microwave electric field sensor allows breakthrough of relaxation time limits for electromagnetic induction transparent phenomena, realizing real-time detection of signals within the range of 10 MHz. Moreover, the existing Ridborg heterodyne detection microwave detection method cannot distinguish the image frequency. Inventive content [0003] The present invention is based on the Ridurg A...
