The invention relates to the technical field of quantum lossless sensing, and provides a quantum lossless sensor which comprises a magnetizer, a diamond probe, a laser module, a microwave module, a microwave antenna, a photoelectric detection module, a light path unit, a lock-in amplifier, a frequency locking module and a data processing module. According to the scheme, an ODMR sweep frequency spectrum line does not need to be drawn when the leakage magnetic field is measured each time, and the tracking of the changed microwave resonance frequency can be quickly realized through the comparison of the target data and the demodulation data, so that the time for obtaining the new microwave resonance frequency is greatly shortened, and the magnetic flux leakage detection efficiency of equipment is improved.
本发明涉及量子无损传感技术领域,方案为一种量子无损传感器,包含磁化器、金刚石探头、激光模块、微波模块、微波天线、光电探测模块、光路单元、锁相放大器、频率锁定模块以及数据处理模块;本方案无需每次测量漏磁场都得绘制ODMR扫频谱线,其可通过目标数据与解调数据的比对,来快速实现对变化的微波共振频率的跟踪,极大缩短了对新的微波共振频率的获取时间,提高了设备的漏磁检测效率。
