摘要：
富含缺陷的半导体的光探测磁共振（ODMR）光谱正越来越多地被用于实现各种实用的量子传感装置。一个典型例子是，基于金刚石中氮-空位（NV）缺陷的紧凑型磁力计正在持续开发，用于以高精度和高灵敏度遥感磁信号。在这些应用中，具有ODMR活性的材料被集成到整个仪器中，以形成自包含传感器。然而，一些新兴应用要求传感材料与外部目标物体发生物理接触，因此需要一种独立的读出装置。在此，我们提出一种ODMR测量仪，这是一种专为方便、非接触地监测目标物体中的ODMR而设计的紧凑型装置，并展示了其在利用NV缺陷进行温度监测方面的应用。我们的原型由一个手持读出头（集成所有必要光学元件和一个微波天线）以及一个连接至笔记本电脑的控制箱组成，主要采用商用现成组件制造。我们使用富含NV的块体金刚石作为目标物体测试该装置，在静态条件下展示出10 mK/√Hz的温度灵敏度，并证明了手持操作的可行性。文中讨论了测量速度、灵敏度和准确性方面的限制。所提出的装置可立即用于需要精确测温的医疗和工业应用，并可扩展至磁场测量。
英文摘要：
Optically detected magnetic resonance (ODMR) spectroscopy of defect-rich semiconductors is being increasingly exploited for realising a variety of practical quantum sensing devices. A prime example is the on-going development of compact magnetometers based on the nitrogen-vacancy (NV) defect in diamond for the remote sensing of magnetic signals with high accuracy and sensitivity. In these applications, the ODMR-active material is integrated into the overall apparatus to form a self-contained sensor. However, some emerging applications require the sensing material to be in physical contact with an external object of interest, thus requiring an independent readout device. Here we present an ODMR-meter, a compact device specially designed to allow convenient, contactless monitoring of ODMR in a target object, and demonstrate its application to temperature monitoring with NV defects. Our prototype is composed of a handheld readout head (integrating all the necessary optical components and a microwave antenna) and a control box connected to a laptop computer, all made primarily from commercial off-the-shelf components. We test our device using an NV-rich bulk diamond as the object, demonstrate a temperature sensitivity of $10~{\rm mK}/\sqrt{\rm Hz}$ in static conditions, and demonstrate the feasibility of handheld operation. The limitations to measurement speed, sensitivity and accuracy are discussed. The presented device may find immediate use in medical and industrial applications where accurate thermometry is required, and can be extended to magnetic field measurements.
