Multi-position diffusion spectral data processing, modeling, and predicting method and processing device

[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...
