Embodiment Construction

[0048] 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.

[0049] According to an embodiment of the present disclosure, the first radial position and the second radial position at different positions from the light source can be arbitrarily selected, spectral data at the two radial positions are obtained, and differential processing is performed on them. The inventors have found that this differential processing can also effectively remove various interferences (especially, common-mode interference). Compared with the technology disclosed in Chinese patent application CN1699973A, the trouble of determining the...

Abstract

The invention discloses a multi-position diffusion spectral data processing, modeling, and predicting method and a processing device. The method comprises the following steps: irradiating a medium containing specific components by probe light to obtain first spectral data of the medium in a first radial direction and second spectral data of the medium in a second radial direction, wherein the first radial direction and the second radial direction are chosen at random, and subjecting the first spectral data and second spectral data to a differential treatment.

Description

technical field [0001] The present disclosure generally relates to the field of spectral detection, and in particular, to spectral detection methods, component concentration modeling and prediction methods, and processing devices for spectral detection. Background technique [0002] The spectral detection method has the advantages of being green and pollution-free, not destroying the sample, fast detection speed, simultaneous quantitative analysis of multiple components, no need to use any reagents or test paper, 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. Near-infrared spectroscopy is considered to be the most promising non-invasive detection technology for chemical components in the human body one. ...
