面向脑磁检测的全光学原子磁强计阵列化微小型集成方法研究

Atomic magnetometer is the ideal magnetic sensitive device fro the new generation of magnetoencephalography. It is important practical needs and strategic significance to effectively treat the human nervous system disease and promote the new generation of artificial intelligence technology revolution. The whole optical atomic magnetometer has the characteristics of high signal-to-noise ratio and non-interference in brain magnetic detection. However, as a result of the complex optical path design, the whole optical atomic magnetometer is not easily to integrate, which restricts the application of microscale integration in the field of brain magnetic detection. Aiming at the requirement of the microscale integration of the whole optical atomic magnetometer, the scheme of the double optical path atomic magnetometer based on modular design is proposed. By modularization design, the atomic magnetometer head can be decomposed into excitation/detection, physical optical optical path and atom cell module. On the basis of modular design, an array microscale integration scheme is proposed.

原子磁强计是新一代脑磁探测的理想磁敏感器件，对于有效治疗人类神经系统疾病和推动人工智能新一轮技术革命具有重要的现实需求和战略意义。而全光学原子磁强计在脑磁探测方面具有高信噪比高灵敏度和不易受磁场干扰的特点。但是全光学原子磁强计由于较为复杂的光路设计导致其大体积、不易集成，限制了其在脑磁检测方面阵列化微小型集成的应用要求。本课题针对全光学原子磁强计阵列化微小型集成的要求，提出基于模块化设计的全光学双光路原子磁强计设计加工方案。通过模块化设计，按功能将原子磁强计表头分解为激发、检测模块、物理光路模块和原子气室模块，并且在的模块化表头设计加工的基础上，提出基于片上键合的阵列化微小型集成方案。研究全光学原子磁强计在阵列化微小型集成的新方法，为未来全光学原子磁强计在脑磁探测方面的应用提供方法参考。
