Instrument independent diffuse reflectance spectroscopy [PDF]
Journal of Biomedical Optics, 2011 Diffuse reflectance spectroscopy with a fiber optic probe is a powerful tool for quantitative tissue characterization and disease diagnosis. Significant systematic errors can arise in the measured reflectance spectra and thus in the derived tissue physiological and morphological parameters due to real-time instrument fluctuations.

Morphological and optical properties of porous hydroxyapatite/cornstarch (HAp/Cs) composites
Journal of Materials Research and Technology, 2020 This paper presents the correlation between the morphological characteristics and the diffuse reflectance (optical properties) of the porous hydroxyapatite/cornstarch (HAp/Cs) composites with various starch proportions (30, 40, 50, 60, 70, 80 and 90 wt%).

Diffuse reflectance mid-infrared spectroscopy is viable without fine milling
Soil Security, 2023 While diffuse reflectance Fourier transform mid-infrared spectroscopy (mid-DRIFTS) has been established as a viable low-cost surrogate for traditional soil analyses, the assumed need for fine milling of soil samples prior to analysis is constraining the ...

Diffuse reflectance spectroscopy: toward real-time quantification of steatosis in liver [PDF]
Transplant International, 2015 Assessment of fatty liver grafts during orthotopic liver transplantation is a challenge due to the lack of real-time analysis options during surgery. Diffuse reflectance spectroscopy (DRS) could be a new diagnostic tool to quickly assess steatosis.
