DIFFERENTIAL-REFLECTANCE SPECTROSCOPY AND REFLECTANCE-ANISOTROPY SPECTROSCOPY ON SEMICONDUCTOR SURFACES

Surface Review and Letters, 1999
The development and the state of the art of surface methods based on the reflection of light are briefly reviewed. A short account is given of the main experimental and theoretical results obtained on semiconductor surfaces over about three decades.

Specular Reflection and Diffuse Reflectance Spectroscopy of Soils

Applied Spectroscopy, 2005
Studies on the occurrence and effects of specular reflection in mid-infrared spectra of soils have shown that distortions due to specular reflection occur for both organic (humic acid) and non-organic fractions (carbonates, silica, ashed fraction of soil). The results explain why the spectra of CaCO 3

Cartilage Analysis by Reflection Spectroscopy

Clinical and Biomedical Spectroscopy and Imaging IV, 2015
A cartilage bioreactor with analytical functions for cartilage quality monitoring is being developed. For determining cartilage composition, reflection spectroscopy in the visible (VIS) and near infrared (NIR) spectral region is evaluated. Main goal is the determination of the most abundant cartilage compounds water, collagen I and collagen II ...

Reflection Spectroscopy of Analgesized Skin

Microvascular Research, 2001
Analgesized skin, when subjected to heat stimuli, responds by increasing skin perfusion. This response does not originate from increased perfusion in superficial capillaries, but rather in the deeper lying vessels. The aim of this study was to assess changes in blood chromophore content, measured by reflection spectroscopy, in relation to the perfusion

Diffuse-reflectance spectroscopy in the infrared

Talanta, 1982
The theory, and the problems encountered in the development of diffuse-reflectance spectroscopy in the infrared region as an analytical technique, are reviewed. The introduction of Fourier-transform infrared spectrometers has eliminated the difficulty of detecting small scattered intensities, and diffuse-reflectance measurement is now a routine method.

Reflectance spectroscopy of pancreatic microcirculation

Journal of Applied Physiology, 1996
A technique employing diffuse reflectance spectroscopy (DRS) is described to assess and mirror dynamic changes of pancreatic tissue perfusion. An especially designed reflectance spectrophotometer was initially used to derive the quantitative relation between hemoglobin concentration ([Hb]) and reflectance measurements in vitro.

Reflection anisotropy spectroscopy

Reports on Progress in Physics, 2005
Reflection anisotropy spectroscopy (RAS) is a non-destructive optical probe of surfaces that is capable of operation within a wide range of environments. In this review we trace the development of RAS from its origins in the 1980s as a probe of semiconductor surfaces and semiconductor growth through to the present where it is emerging as a powerful ...
