Problems solved by technology

In existing spectroscopic measurement techniques, ordinary mercury lamps or xenon lamps are usually used as excitation light sources. This kind of equipment can only excite weak signals, and cannot detect the characteristic spectral peaks (wavelength or energy information) emitted from multiple states of matter. This Defects affect researchers' clear physical understanding of the distribution of elements inside matter

Abstract

The invention discloses a long-distance autonomous multi-state spectrum detection system. The system comprises a high-energy pulse laser, a combined lens and a spectrum analyzer, the high-energy pulse laser is used for generating high-energy laser and aligning the high-energy laser with a to-be-measured multi-state sample at a distance to generate a high-temperature plasma state, so as to excite characteristic signal light waves of a multi-state material; the combined lens is used for receiving characteristic signal light waves radiated by a remote to-be-measured multi-state sample in a high-temperature plasma state and transmitting the characteristic signal light waves to the spectrum analyzer; and the spectrum analyzer is used for analyzing and identifying characteristic signal light waves radiated by the to-be-detected multi-state sample. According to the invention, high-energy laser emitted by the high-energy pulse laser excites a distant sample to generate a high-temperature plasma state, a characteristic signal spectrum is emitted, the characteristic signal spectrum is subjected to a series of processing through the combined lens and then is emitted to the spectrum analyzer, and fine measurement of a multi-state spectrum is realized.
