摘　　要：针对里德伯原子EIT-AT法射频电场测量方案中,测量频点带宽窄的问题,提供了一种宽带连续射频电场测量方法,并在TEM室中演示了量子射频电场探测系统的测量技术。该方法通过在TEM室内放置电场探头,基于非共振射频与里德伯原子的相互作用模型,在外加射频电场作用下,里德伯原子的能级产生偏移,根据光谱偏移变化量,反推出射频电场的强度大小。基于该方案实现了50~500 MHz范围内的连续频率不间断电场测量,极大的扩展了量子场强的应用范围,该方案同样可扩展至1 GHz以上的微波电场测量,该量子场强探头为光纤可解耦的结构,可以实现管道机箱等狭小空间的电场环境探测。To solve the problem of the limited bandwidth,when measuring the RF electric field using Rydberg atom EIT-AT method,a method of continuous broadband RF field measurement is proposed.The experiment of quantum Rydberg RF electric field measurement is carried out in TEM cell.The fiber-coupled quantum probe is placed in TEM cell,based on the a model of non-resonance interaction between RF field and Rydberg atoms,According to the shifted spectrum frequency of Rydberg in electric field,the electric field can be calculated.The method can be used to the measurement of electric field for the continuous frequency between 50 MHz and 500 MHz,which enlarge the range of application of quantum field measurement,the propose can also be applied in other band electric field measurement,such as frequency above 1 GHz,the fiber coupled atom-based electric probe can also be used for electric field environment detection in narrow and small space,such as pipes and mini case.
