Abstract

The invention discloses a compact laser induced breakdown spectroscopy measurement system. A control module controls a laser light source according to a preset work instruction to emit a laser beam to a focusing acquisition device; the focusing acquisition device focuses and irradiates the laser beam onto a sample to be tested, and the focusing acquisition device collects and sends the plasma light generated by the sample to be tested to a spectrum acquisition module; and the control module of analyzes the spectral data received by the spectrum acquisition module, so as to obtain the detection result of the sample to be tested. Therefore, the compact laser induced breakdown spectroscopy measurement system can solve the problem that the laser breakdown spectrum measurement technology of the prior art has separated laser focusing and spectrum acquisition, which lead difficulty in integration and miniaturization.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a compact laser-induced breakdown spectrum measurement system. Background technique [0002] Laser Induced Breakdown Spectroscopy (LIBS) is a typical emission spectrum analysis method. This technology focuses high-energy pulsed laser light on the surface of the measurement sample to ablate the sample to generate plasma. During the cooling and expansion process of the generated laser-induced plasma, a series of light with specific wavelengths will be emitted. By collecting and detecting these signal lights, the corresponding Spectral signal, and then corresponding data processing and analysis, the corresponding concentration of the constituent elements in the measurement sample can be obtained. [0003] LIBS technology has the advantages of no need for complex sample pretreatment, multi-element simultaneous analysis, measurement of solid, liquid, and gaseous samples, and remote ...
