[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] The Rydberg atomic electromagnetic induction transparency effect is a special quantum coherence effect, mainly caused by the interaction of atoms with coupled and probed light.

[0024] Effect principle: When two laser beams interact with atomic resonance, the absorption phenomenon that should have appeared at the resonance frequency of the probe light will disappear, forming a transparent window.

[0025] Characteristics of Rydberg atoms: Rydberg atoms are excited atoms whose outer electrons are excited to a very high principal quantum number. They have excellent properties such as long spontaneous emission lifetime, high polarizability, and strong transition dipole moment. These properties give the EIT effect of Rydberg atoms many special properties, such as the generation of nonclassical light, cooperative effect, and nonlinear absorption.

[0026] Application areas: The EIT effect of Rydberg atoms has wide applications in slowing down and storing light pulses, enhancing the refractive index of media, microwave detection and the preparation of single-photon sources. By utilizing the sensitivity of Rydberg atoms to external electromagnetic fields, precise measurement of microwave electric field strength can also be achieved.

[0027] Research progress: In recent years, researchers have realized the EIT effect of Rydberg atoms in different media and studied in depth how it varies with coherent electromagnetic fields and system parameters.

[0028] The Rydberg atom electromagnetic induction transparency effect radio frequency electric field polarization direction sensing device is mainly used to measure the polarization direction of radio frequency electric fields. This device utilizes the sensitivity of Rydberg atoms to external electromagnetic fields and achieves accurate sensing of the polarization direction of radio frequency electric fields through the electromagnetic induction transparency (EIT) effect. Rydberg atoms have characteristics such as high polarizability and sensitive response to external electromagnetic fields, which gives this device a unique advantage in radio frequency electric field measurement. By measuring and analyzing the EIT spectral characteristics of Rydberg atoms under the action of radio frequency electric fields, the polarization direction of radio frequency electric fields can be inferred, providing a new measurement method and technical support for microwave detection, wireless communication and other fields.

[0029] The Rydberg atomic electromagnetic induction transparent effect (EIT) radio frequency electric field polarization direction sensing device can be used not only for microwave electric field polarization measurement, but also for the study of microwave optical properties of solid materials, electric field intensity control, and biomedical imaging, among other fields. It has broad application prospects and significant scientific value. However, the Rydberg atomic EIT radio frequency electric field polarization direction sensing device often encounters some problems in practical use. Below are some common problems and their causes: 1. Limited Measurement Accuracy: Although the device has the potential for high-precision measurement, in practical applications, the measurement accuracy may be limited by various factors. The main reasons may be environmental noise, system nonlinear characteristics, equipment calibration errors, and the stability of the atomic system, all of which can affect measurement accuracy. For example, environmental noise may interfere with the measurement signal, leading to increased measurement errors. 2. System Stability Issues: After long-term operation, the system may experience a decrease in stability, affecting the reliability of the measurement results. The main reason may be that the stability of the atomic system is affected by various factors, such as temperature fluctuations, laser frequency stability, and interatomic interactions. These factors may cause changes in atomic energy levels, thus affecting the stability of the EIT effect and the accuracy of the measurement results. 3. Equipment Complexity and Cost: This device typically involves complex experimental setups and expensive equipment, increasing the difficulty of use and maintenance. The main reason is likely that achieving high-precision measurements requires a high-precision laser source, a stable magnetic field environment, and a complex electronic control system. The integration and calibration of these components require specialized technology and experience, resulting in high equipment costs and operational complexity. 4. Limited Measurement Range: Although the device is sensitive to microwave electric fields of specific frequencies, the measurement range may be limited by the atomic energy level structure and the characteristics of the EIT effect. The main reason is likely that the energy level spacing of Rydberg atoms and the characteristics of the EIT effect determine their sensitivity to microwave electric fields of specific frequencies; for electric fields outside this frequency range, accurate measurement results may not be obtained.

[0030] Currently, various types of Rydberg atom electromagnetic induction transparency effect radio frequency electric field polarization direction sensing devices exist on the market, aiming to achieve high-precision and high-sensitivity microwave electric field measurement and polarization direction detection. Below are some common Rydberg atom electromagnetic induction transparency effect radio frequency electric field polarization direction sensing devices: 1. Microwave detection device based on the strong interaction of the Rydberg atom ensemble: This device utilizes the strong interaction caused by the many-body effect in the Rydberg atom ensemble. By introducing a strong noise microwave field, it significantly enhances the weak detection signal and improves the signal-to-noise ratio. It operates near the system's critical point and can perform continuous microwave measurements. 2. Radio frequency electric field measurement device based on the Rydberg atom EIT effect: This type of device utilizes the EIT effect of the Rydberg atom. By modulating the Rydberg energy level with a radio frequency field, it forms the radio frequency sideband of the EIT spectrum or the two-photon EIT-AT spectrum. Based on the spectral characteristics, it can measure parameters such as radio frequency electric field intensity and polarization direction.

[0031] Although various types of Rydberg atom electromagnetic induction transparency effect radio frequency electric field polarization direction sensing devices exist on the market, they face numerous challenges in practical application, including the issues mentioned above: 1. Measurement accuracy and stability: While the Rydberg atom EIT effect has the potential for high-precision measurement, practical applications may be affected by environmental noise, system nonlinear characteristics, and equipment calibration errors, leading to limitations in measurement accuracy and stability. 2. Equipment complexity and cost: These devices typically involve complex experimental setups and expensive equipment, such as high-precision laser sources, stable magnetic field environments, and complex electronic control systems, increasing the difficulty and cost of use and maintenance. 3. Limited measurement range: The energy level structure and EIT effect characteristics of Rydberg atoms determine their sensitivity to microwave electric fields of specific frequencies; accurate measurement results may not be obtained for electric fields outside this range. When selecting a Rydberg atom electromagnetic induction transparency effect radio frequency electric field polarization direction sensing device, a comprehensive consideration must be given to factors such as practical application requirements, device performance, compatibility and scalability, cost, and maintenance.

[0033] Please see Figure 3In this embodiment, the adjustment assembly includes a mounting block 501, a first connecting block 502, a second connecting block 503, a third connecting block 504, a second drive motor 505, and a third drive motor 506. The upper end of the mounting block 501 has three sets of mounting holes 507 at its four corners for mounting and fixing the mounting block 501. The mounting block 501 is detachably connected to the support platform 1 through the mounting holes 507. The upper end of the mounting block 501 is fixedly connected to the first connecting block 502, and the first connecting block 502 and the third connecting block 504 are connected by the second connecting block 503. The first connecting block 502 and the second connecting block 503 are connected by a rotatable connection.

[0034] Please see Figure 5 In this embodiment, the temperature control component includes a control module 601 and a condenser tube 602. The condenser tube 602 is embedded in the lower part of the atomic gas chamber 3. One end of the condenser tube 602 extends through the atomic gas chamber 3 and is fixedly connected to the control module 601 for controlling the temperature and working state of the condenser tube 602. The control module 601 is equipped with a temperature control module, a sensor module, a signal processing module and an actuator drive module.

[0035] When working, first place the device in a stable position so that the support platform 1 provides stable support for the laser 2, the atomic gas chamber 3 and the photodetector 4.

[0036] Then, by turning on the switches of each structure through the external PLC control cabinet, the induction test of the polarization direction of the frequency electric field is started. First, a laser of a specific wavelength is emitted by the laser 2 into the atomic gas chamber 3, which interacts with the Rydberg atoms in the atomic gas chamber 3.

[0037] During the interaction between Rydberg atoms and the laser beam, the temperature is controlled by the temperature control component, the condenser 602 is adjusted to a suitable temperature by the control module 601 to cool the inside of the atomic gas chamber 3, the pressure inside the atomic gas chamber 3 is controlled by the pressure controller 8 to adjust the atomic density to the optimal state, and the internal magnetic field generation module is controlled by the control panel 7.

[0038] Then, the photodetector 4 is used to receive and detect the probe light transmitted from the atomic gas chamber 3.

[0039] During the operation of the laser 2, atomic gas chamber 3, and photodetector 4, the angles of the laser 2 and photodetector 4 are adjusted by adjusting the components.

The first drive motor 14 drives the rotating shaft 13 to rotate, thereby driving the atomic gas chamber 3 to rotate synchronously to adjust its angle. By adjusting the angles of the laser 2 and photodetector 4, the actual measurement environment and different measurement requirements can be adapted.

[0040] Through the above steps, the angles of the laser 2 and photodetector 4 can be adjusted by setting the adjustment component, and the angle of the atomic gas chamber 3 can be adjusted by setting the first drive motor 14. This allows the laser 2, atomic gas chamber 3, and photodetector 4 to be adjusted according to different scenarios and measurement requirements. By setting the temperature control component and pressure controller 8 on the atomic gas chamber 3, the atomic density can be adjusted by changing the temperature and gas pressure to keep it in an optimal state. This ensures that a sufficient number of atoms participate in the interaction while avoiding collisions and interference caused by excessive density. This improves measurement flexibility, optimizes measurement accuracy, and enhances adaptability, making the measurement results more comprehensive and accurate. This addresses the problem that existing Rydberg atomic electromagnetic induction transparency effect radio frequency electric field polarization direction sensing devices typically have fixed angles for the laser 2, atomic gas chamber 3, and photodetector 4. This limits the adaptability of the device to different measurement environments and conditions, and makes it impossible to flexibly adjust according to actual needs. This may lead to poor measurement results or inability to measure in certain specific situations, and it may not be able to fully cover all possible polarization directions, thus affecting the comprehensiveness and accuracy of the measurement.
