Problems solved by technology

[0010] However, when multiple disturbances exist at the same time, especially some factors that affect optical parameters, such as temperature, blood oxygen, etc., they have different action modes at each radial detection position, and the actual measurement results are their aliasing As a result, there are currently no effective countermeasures to eliminate them all

Embodiment Construction

[0036]Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. It should be understood, however, that these descriptions are exemplary only, and are not intended to limit the scope of the present disclosure. Also, in the following description, descriptions of well-known structures and techniques may be omitted to avoid unnecessarily obscuring the concepts of the present disclosure.

[0037] When performing spectral measurement on a measured medium containing specific components, various interference factors that can affect the optical properties of the measured medium will affect the spectral measurement. In the obtained spectral data, the interference caused by these interference factors may exist at the same time.

[0038] In the following, such factors are mainly discussed, which basically only affect the optical parameters of the measured medium, such as absorption coefficient and / or scattering coefficient (or, reduced scatterin...

Abstract

The invention provides a spectral-data interference suppression method, a modeling method, a forecasting method and a processing device. According to the embodiment, the spectral-data interference suppression method can include the steps that the interference mode of at least one interference factor in spectral measurement is determined, and the interference mode limits interference at multiple radial positions away from a light source; diffusion spectral data of a measured medium containing specific ingredients is obtained; on the basis of the interference mode, information relative to the specific ingredients is extracted from the diffusion spectral data, wherein interference of the at least one interference factor in the diffusion spectral data is inhibited in the extracted information.

Description

technical field [0001] The present disclosure generally relates to the field of spectral detection, and in particular, to an interference suppression method for spectral data, a component concentration modeling and prediction method, and a processing device. Background technique [0002] The spectral detection method has the advantages of being green and pollution-free, not destroying samples, fast detection speed, simultaneous quantitative analysis of multiple components, no need to use any reagents or test papers, and continuous and real-time monitoring. It is a non-invasive detection technology in the true sense. In the field of biomedicine, the use of near-infrared absorption spectroscopy has successfully achieved rapid and non-invasive detection of biochemical indicators such as blood oxygen saturation in biological tissues. Currently, near-infrared spectroscopy is considered to be one of the most promising non-invasive detection techniques for physiological components ...
