Abstract
Digital signals play an extremely important role in the integration and multi-functionality of industrial instrumentation. With the expansion of industrial application scenarios, non-interference detection of digital signals in certain extreme environments has become the need of the hour. This paper demonstrates a method for non-interference Detection of transmission line digital signals based on nitrogen-vacancy (NV) centers in diamond. The optical readability and the sensitivity to magnetic fields of the NV centers are utilized to characterize the current-induced weak magnetic field signals by fluorescence signals in a confined space. By combining quantum sensing technology, quantum imaging technology and electromagnetic induction technology through NV centers, it is able to realize high sensitivity and high precision multi-point measurement and dynamic monitoring of electrical signals. The temporal resolution of the digital signal was evaluated by regulating the duration of the input current in the transmission line, and the lowest transmission current in a single transmission line and two transmission lines in a 1.2 mm × 1.2 mm imaging field of view was explored. The experimental results show that the time resolution of the detected digital signals is up to 30 μs. This research highlights the potential value of NV centers in digital signal processing and provides new research directions for detecting digital signals in extreme environments.
