无线电频率（RF）用户的一个强大工具是能够可视化这些分布。在这里，使用与铯原子双共振相关的荧光演示了电路板上RF波的2-D可视化。不可见的RF波被上转换成可以用光学相机观察的近红外光。此外，使用直流磁场针对RF磁场分量的每个极化单独捕获2-D可视化图像。二维偏振测量的图像与磁场强度分布的有限元计算一致。
A powerful tool for users of radio frequencies (RFs) is the ability to visualize those distributions. Here, the 2-D visualization of RF waves on a circuit board is demonstrated using the fluorescence associated with the double resonance of cesium atoms. The invisible RF waves are upconverted into near-infrared light that can be viewed with an optical camera. In addition, a 2-D visualization image is captured separately for each polarization of the RF magnetic field component using a direct-current magnetic field. The images of the 2-D polarimetry are consistent with finite-element calculations of the distribution of the magnetic field strength.
