Embodiment Construction
[0040] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0041] Raman spectroscopy combined with laser technology can easily achieve quantitative analysis of substances. The existing Raman quantitative analysis method needs to perform background subtraction, and then perform quantitative analysis according to the peak area of the Raman peak. The current automated background subtraction algorithm is based on the spectral shape of the Raman spectrum. If the spectral shape changes, many errors may occur, resulting in a decrease in the accuracy of the Raman spectral quantitative analysis system. Based on this, the present invention provides a method and system for quantitative analysis of Raman spectra based on direct extraction of spectral peak heights. The analysis system can improve the precision of the Raman spectroscopy quantitative analysis system.
