摘要光谱预处理和波长选取方法在近红外光谱分析技术中相当重要. 本文综述了常用的NIR
预处理和波长选取方法及这一领域的最新进展, 详细介绍正交信号校正(OSC), 净分析信号(NAS) …

Raman and Infrared (IR) spectroscopies provide information about the structure, functional
groups and environment of the molecules in the sample. In combination with a microscope …

Pre-processing of near-infrared (NIR) spectral data has become an integral part of
chemometrics modeling. The objective of the pre-processing is to remove physical …

Sporadic ocean color events with characteristic spectra, in particular algal blooms, call for
quick delivery of high-resolution remote sensing data for further analysis. Motivated by this …

Raman spectra of biological materials are very complex, because they consist of signals
from all molecules present in cells. In order to obtain chemical information from these …

Major food adulteration and contamination events seem to occur with some regularity, such
as the widely publicised adulteration of milk products with melamine and the recent …

Vibrational spectroscopy methods are widely investigated as fast and non-destructive
alternatives for postharvest quality evaluation. As these methods measure spectral …

Recent years have seen substantial progress toward the application of infrared (IR) and
Raman spectroscopy as useful analytical tools in biomedical research. Vibrational …
