论文摘要
我们开发了一个平行的光学检测到的磁共振（PODMR）光谱仪，以解决，操纵和读取并联钻石中的单个氮散布（NV）中心的阵列。在该光谱仪中，我们使用一系列微透镜来在物镜上生成20 * 20激光斑点（LSL），然后将LSL与单个NV中心对齐。 NV中心的量子状态通过ω形共面线圈的均匀微波场操纵。作为实验演示，我们在视野中观察到80个NV中心。其中，沿外部磁场的18个NV中心的磁共振（MR）光谱和拉比振荡并联。与共聚焦技术相比，这些结果可直接用于实现平行量子传感和多次加速。关于纳米级MR技术，PODMR对于高吞吐量单分子MR谱和成像至关重要。
We develop a parallel optically detected magnetic resonance (PODMR) spectrometer to address, manipulate and read out an array of single nitrogen-vacancy (NV) centers in diamond in parallel. In this spectrometer, we use an array of micro-lens to generate 20 * 20 laser-spot lattice (LSL) on the objective focal plane, and then align the LSL with an array of single NV centers. The quantum states of NV centers are manipulated by a uniform microwave field from a Ω-shape coplanar coil. As an experimental demonstration, we observe 80 NV centers in the field of view. Among them, magnetic resonance (MR) spectrums and Rabi oscillations of 18 NV centers along the external magnetic field are measured in parallel. These results can be directly used to realize parallel quantum sensing and multiple times speedup compared with the confocal technique. Regarding the nanoscale MR technique, PODMR will be crucial for high throughput single molecular MR spectrum and imaging.
