Embodiment Construction

[0015] Invention idea of ​​the present invention is:

[0016] The rapid sample search method for Raman spectroscopic substance detection of the present invention compresses the information of the Raman curve, and counts the information of thousands of data points into peak distributions at different intensities, thereby reducing the information search calculation of the curve while retaining the main features of the Raman curve. Thus, rapid sample search for Raman spectroscopic substance detection is realized.

[0017] Using the rapid sample search method for Raman spectroscopic substance detection of the present invention, when building a feature library, in addition to saving traditional curve data, the following information must also be saved:

[0018] 【1】The total number of peaks of the characteristic curve of this sample.

[0019] [2] The highest peak of the peak of the characteristic curve of this sample is the reference highest value P, which is divided into 3 heights...

Abstract

The invention relates to a quick lookup method for a Raman spectrum substance detection sample. The quick lookup method comprises the following steps: building a feature library; placing a substance sample to be detected in a spectrograph testing area, and carrying out Raman spectrum collection, traversing the group of data series to obtain the maximum peak value Qmax of the substance sample to be detected, and obtaining the minimum peak value according to a formula; within the range from Qmin to Qmax, obtaining the position and value of each peak, recording the total quantity Mall of the lower peaks to carry out total quantity match of the peaks; matching the quantity of the peaks in averaged three height intervals within the range from the Qmin to the Qmax; looking up the substance sample to be detected from the retained specified substance samples. The quick lookup method can accelerate the sample lookup speed, improve measuring instantaneity, and expand the application area of Raman measurement.

Description

technical field [0001] The invention relates to the technical field of Raman spectroscopic substance detection, in particular to a rapid sample search method for Raman spectroscopic substance detection. Background technique [0002] Raman Spectra (RamanSpectra), is a kind of scattering spectrum. Raman spectroscopy is based on the Raman scattering effect discovered by Indian scientist C.V. Raman (Raman). It analyzes the scattering spectrum different from the frequency of the incident light to obtain molecular vibration and rotation information, and is applied to the study of molecular structure. a method of analysis. Through the analysis of Raman spectrum, the vibration and rotation energy level of the substance can be known, so that the substance can be identified and the properties of the substance can be analyzed. In the application of Raman spectroscopy for material detection, it is necessary to realize the storage of characteristic information of various substances and...
