Abstract

The invention relates to a laser induction multiple spectrum united fingerprint network online detecting material method which comprises the following steps of: firstly, irradiating a detected sample with laser and simultaneously utilizing a spectrograph to detect a fluorescence excitation spectrum, a plasma spectrum or a Raman spectrum of the detected sample; and secondly, comparing the spectrums of the detected sample with the traditional spectrums. In the first step, a computer or a smart mobile phone is used for collecting a spectrum signal obtained by the spectrograph and transmitting the signal to a central server, the central server is connected with a default multiple spectrum united fingerprint database through a data switching system, and the default multiple spectrum united fingerprint database is internally provided with standard spectrum fingerprint data of the fluorescence excitation spectrum, the plasma spectrum and the Raman spectrum of materials and substances. In thesecond step, the central server compares the spectrum image signal with the standard spectrum fingerprint data in the database for analysis, then determines the material property of the detected sample and returns the comparison result to the computer.

Description

Technical field: [0001] The invention relates to the field of physics, in particular to spectral measurement technology, in particular to a method for online detection of materials by laser-induced multi-spectral combined fingerprint network. Background technique: [0002] Light is a kind of electromagnetic radiation wave with certain energy. The energy of different wavelengths of light corresponds to a certain quantization energy level difference of electrons in molecules or atoms. When light acts on the substance to be measured, it will cause reflection, absorption and scattering and other phenomena, resulting in the change of the incident light signal. The change of the incident light signal directly reflects the absorption, reflection or scattering of the electromagnetic radiation of the compound atoms or molecules. Spectral technology is to measure the change and obtain the light absorption, reflection or scattering. Spectra for qualitative or quantitative analysis and ...
