摘要： A scanning type laser induced spectrum surface range analysis and detection system includes a laser emitting head connected to an external laser inducing light source, which generates lasers emitted through the laser emitting head, so as to generate laser induced plasma. A focusing optical device converges induction excited laser beams emitted by the laser emitting head onto a surface of a tested sample. Then, a reflector collects wide spectral range induced plasma scattered light signals of the tested sample and converges the signals into a light collecting device. The light collecting device converges induced plasma scattered light into an optical fiber and transmits the induced plasma scattered light to an external spectrograph; and the external spectrograph divides a spectrum formed by the plasma to obtain spectral strength data of different wavelengths.
