摘要： To realize multi-point real-time measurements of LIBS (Laser-induced Breakdown Spectroscopy), this paper introduces software to control LIBS multi-point measurement based on Qt cross-platform C++ application development environment, including the overall structure, functional module and concrete implementation. Multi-threaded technology, database, QWT open source database and communication technology were used in the measurement system. It realizes the cascade of spectrometer and motion controller, and completes the fast planning of different measurement trajectories and real-time acquisition of display spectral data. Experiments indicate that the measurement system software provides a user-friendly interface, stable performance, and can realize the real-time multi-point measurement of LIBS, while it can reduce the measurement errors caused by sample in homogeneity, laser and spectrometer stage differences, etc, and improve the measurement accuracy.
