Abstract

The invention discloses a Raman spectrum detection system and method. The system includes a first measuring device, a second measuring device, and a spectrum analysis device (8), and the first measuring device includes a first laser (1), an optical path converter (3), a first optical focuser (4) . An optical coupler (7), the second measuring device includes a second laser (9), a second optical focuser (11), and a displacement guide rail (12). The Raman spectrum detection system and method of the present invention can bypass the influence of the Raman spectrum of the container when detecting the substance in the opaque container, and can also eliminate the influence of the fluorescence of the substance itself.

Description

technical field [0001] The invention relates to the technical field of laser excitation spectrum detection, in particular to a Raman spectrum detection system and method. Background technique [0002] When performing Raman spectrum detection on the substance inside the container for material analysis, it is necessary to be able to bypass the influence of the Raman spectrum of the container. However, traditional Raman spectroscopy can only detect the superficial information of the sample, or can only penetrate the transparent surface to detect the bottom layer. [0003] However, many analytical applications require high chemical specificity and the ability to penetrate multiple layers of opaque samples or opaque packaging materials, such as non-destructive detection of bone disease, search for concealed explosives, and identification of counterfeit drugs in packaging. Traditional Raman spectroscopy detection is in the form of backscattering, which is easy to implement, but t...
