The principle of reflectance spectroscopy is illustrated in Fig. These elements can be illuminated by either a direct or a diffuse light source. Both sources of light will provide specular and diffuse reflection. Diffuse reflectance spectroscopy is a versatile tool that allows us to accurately measure the flux per wavelength of light reflected in a scattered manner from a sample. Whether the sample be almost purely diffuse, as in a lightly packed powder, predominately specular, as in a burnished metal surface, or something in between, such as a glossy.

The diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) is an alternative method to analyse microplastics that are too small for ATR experiments. Analogously to the KBr-pellet technique, microplastics and potassium bromide are mixed. Particle size should be less than 50 μm. Within DRIFTS experiments, this powder blend is filled into a special cup . Soil reflectance spectroscopy is a well-known technique to assess soil properties rapidly and quantitatively in both point (spectroscopy) and spatial (imaging spectroscopy (IS)) domains. The quantitative approach has been developed in the past two decades by many researchers, with much literature on the by:

The key models presented for reflectance spectroscopy are the Hapke model for scattering and reflectance and the Shkuratov model for reflectance. For emittance spectroscopy, the Hapke model forms the backbone upon which hybrid models incorporating Mie T .

Book description This book is aimed at students and researchers who wish to use reflectance and emittance as quantitative tools to measure the properties of surfaces and materials.

For several reasons reflectance spectroscopy is a powerful technique for measuring the characteristic absorption spectrum of a particulate material. The dynamic range of the measurement is extremely large. Multiple scattering amplifies the contrast within weak absorption bands in the light transmitted through the particles, while strong bands.

Applied Spectroscopy includes important information and equations which will be referred to regularly. The book emphasizes reflectance and color measurements due to their common usage in todays spectroscopic laboratories, and contains methods for selectinga measurement technique as well as solar and color measurements.

Diffuse Reflectance – Theory and Applications Diffuse Reflectance – Ideal for Powdered Samples and Intractable Solids Diffuse reflectance is an excellent sampling tool for powdered or crystalline materials in the mid-IR and NIR spectral ranges. It can also be used for analysis of intractable solid samples.

As withFile Size: KB. Reflectance of the surface of a material is its effectiveness in reflecting radiant is the fraction of incident electromagnetic power that is reflected at an interface. The reflectance spectrum or spectral reflectance curve is the plot of the reflectance as a function of wavelength.

This book gives a quantitative treatment of the physics of the interaction of electromagnetic radiation with particulate media, such as powders and soils.

Subjects covered include electromagnetic. The release of the second edition of the Theory of Reflectance and Emittance Spectroscopy is extremely timely, arriving at a time when the previous decade successfully collected a large number of spatially resolved hyperspectral datasets for solid bodies throughout the solar system and is likely to continue to dramatically increase during the next 10  by: 3.

Reflectance and emittance spectroscopy are increasingly important tools in remote sensing and have been employed in most recent planetary spacecraft missions. They are primarily used to measure properties of disordered materials, especially in the interpretation of remote observations of the surfaces of the Earth and other terrestrial : Bruce Hapke.

Reflectance difference spectroscopy (RDS) is a spectroscopic technique which measures the difference in reflectance of two beams of light that are shone in normal incident on a surface with different linear polarizations.

It is also known as reflectance anisotropy spectroscopy (RAS). It is calculated as: = − +, ∈ and are the reflectance in two different polarizations.
