Mining the Information Content Buried in Infrared and Near-Infrared Band Shapes by Temporal, Spatial, and other Perturbations

Technologies and Practical Considerations for Implementing Near‐Infrared Chemical Imaging

“…Another source filtered approach is global NIRCI with OPO laser illumination [16,51]. The narrow wavelength output of an OPO is directed onto a sample.…”

Detection of Melamine in Foodstuffs by Vibrational Spectroscopy

“…A mid-IR hyperspectral imaging spectrometer played a vital role in understanding why the incorporation of melamine in foodstuffs is so dangerous. 5 The key experiments were performed by feeding foods that had been contaminated with a high concentration of melamine to cats. The visible image of a stained (for histopathological examination) thin section taken from the kidney of a cat that had been fed melamine-tainted wheat gluten is shown in Figure 5(a).…”

“…5 Spectra were measured at 2-nm resolution from 1300 to 1600 nm in steps of 1 nm. Figure 9(a) shows the corrected reflectance image at one of these wavelengths (1454 nm).…”
