In recent years, modern spectral analysis techniques, such as ultraviolet–visible (UV-vis)
spectroscopy, mid-infrared (MIR) spectroscopy, near-infrared (NIR) spectroscopy, Raman …

Rock geochemistry can accurately and effectively delineate geological anomalies, providing
clear instructions for geological prospecting and playing a crucial role in mineral resource …

Visible and near-infrared (Vis–NIR) spectroscopy is used to estimate soil organic matter
(SOM). Spectral preprocessing techniques and multivariate modeling methods play …

Water status is critical since it affects photosynthetic efficiency and limits crop yield. Thus it is
essential to calculate the water content of crop fast and nondestructively. In this work …

Nitrogen is the key biochemical component of chlorophyll, protein and enzymes, and it is
widely used as an indicator of photosynthesis and plant nutrient levels. Hyper-spectral data …

In order to identify the freshness grade of eggs nondestructively and rapidly, hyperspectral
imaging technology was used in this article. The hyperspectral data of 200 samples of three …

The maximum carboxylation rate (Vcmax) and the maximum electron transport rate (Jmax)
are representative parameters describing the gas exchange properties of leaves. Non …

Abstract Visible and Near Infra-Red Spectroscopy (Vis/NIRS) technique was investigated as
a non-destructive optical method in order to authenticate argan oil. This study focuses on the …

Spectral pretreatment is of great importance in near infrared (NIR) spectral analysis since
NIR spectra of samples almost always contain overlapped bands due to different chemical …

Since the advent of X-Ray fluorescence (XRF) spectrum analysis technology, with its wide
range of elemental analysis, rapid, nondestructive analysis characteristics, and better …
