Quantum sensing based on nitrogen-vacancy centers in diamond has shown excellent properties. Combined with the imaging technique, it shows exciting practicability. Here, we demonstrate the simultaneously imaging technique of magnetic field and temperature using a wide-field quantum diamond microscope. We describe the operating principles of the diamond microscope and report its sensitivity (magnetic field ${\sim}1.8~\mu \mbox{T/Hz}^{1/2}$ and temperature ${\sim}0.4~\mbox{K/Hz}^{1/2}$ ), spatial resolution (1.3 μm), and field of view ( $400 \times 300~\mu \mbox{m}^{2}$ ). Finally, we use the microscope to obtain images of an integrated cell heater and a PCB, demonstrating its ability in the application of magnetic field and temperature simultaneously imaging at wide-field.

使用宽视野量子金刚石显微镜同时成像磁场和温度

基于金刚石中氮空位中心的量子感测已显示出优异的性能。结合成像技术，它显示出令人兴奋的实用性。在这里，我们演示了使用宽视野量子金刚石显微镜同时进行磁场和温度成像技术。我们描述了钻石显微镜的工作原理并报告了其灵敏度（磁场$ {\ sim} 1.8〜\ mu \ mbox {T / Hz} ^ {1/2} $和温度$ {\ sim} 0.4〜\ mbox {K / Hz} ^ {1/2} $），空间分辨率（1.3μm）和视场（$ 400 \ times 300〜\ mu \ mbox {m} ^ {2} $）。最后，我们使用显微镜获取集成的电池加热器和PCB的图像，证明了其在磁场和温度应用中同时在宽视野下成像的能力。
