Abstract
The invention discloses a small-sized integration breakdown spectrum measurement system based on high voltage electricity induction. A control module controls a high-voltage electric light source to emit a high-voltage electric light beam to a focusing collection device according to a preset work instruction, the focusing collection device focuses and irradiates the high-voltage electric light beam onto a to-be-measured sample, and the focusing collection device collects and transmits plasma light generated by the to-be-measured sample to a spectrum acquisition module; and further, the controlmodule analyzes spectral data received by the spectrum acquisition module to obtain a detection result of the to-be-measured sample. Therefore, the small-sized integration breakdown spectrum measurement system based on the high voltage electricity induction can solve the problem that an existing high-voltage electricity-induced breakdown spectrum measurement technology separates high-voltage electricity focusing from spectrum collection, resulting in difficulty in integration and miniaturization.
Description
technical field [0001] The invention relates to the field of optical technology, in particular to a small integrated breakdown spectrum measurement system based on high voltage electric induction. Background technique [0002] Laser Induced Breakdown Spectroscopy (LIBS) is a typical emission spectroscopy analysis method. This technology generates plasma by focusing high-energy pulse high-voltage electricity on the surface of the measurement sample to ablate the sample, and emits a series of light with specific wavelengths during the cooling and expansion process of the plasma induced by high-voltage electricity. By collecting and detecting these The corresponding spectral signal is obtained from the signal light, and then the corresponding data processing and analysis are carried out to obtain the corresponding concentration of the constituent elements in the measurement sample. [0003] LIBS technology has the advantages of no need for complex sample pretreatment, multi-el...
