[Monte Carlo simulation of the determination of complex mixed solution with hyperspectral technique]

In order to overcome the defects of overlapping spectrum and low signal-to-noise ratio in the analysis of the complex mixed solution with the traditional spectral method, the authors introduce hyperspectral technique to the analysis of complex mixed solution in the present article. The hyperspectral technique can use the information of the analytes carried by multi-mode photons to analyze the solution. Compared with the traditional methods that only use the absorption characteristics for analysis, the hyperspectral technique also use the space information to increase the spectral signal-to-noise ratio and to improve the modeling accuracy and reliability. To verify the feasibility of the analysis of complex mixed solution with hyperspectral technique, the authors take Monte Carlo simulation to simulate the distribution of the diffuse light of the Intralipid-Ink model in the range of 650 -1 100 nm; the distribution of the diffuse light of the complex mixed solution is obviously different at different wavelengths. It is proved that the hyperspectral technique can use characteristic changes with the wavelengths of the analyte, greatly improve the signal to noise ratio, and has the potential to significantly enhance the ability of the component analysis of complex mixed solution.
