dependence of reflectance on the wavelength is called a reflectance spectrum or spectral reflectance curve. The hemispherical reflectance of a surface...

Lambertian reflectance is the property that defines an ideal "matte" or diffusely reflecting surface. The apparent brightness of a Lambertian surface...

percentages represent lower skin reflectance and thus darker pigmentation, whereas higher percentages represent greater skin reflectance and therefore lighter pigmentation...

set of satellite reflectance measurements into estimates of directional-hemispherical reflectance and bi-hemispherical reflectance (e.g.,). These calculations...

Directional-hemispherical reflectance is the reflectance of a surface under direct illumination (with no diffuse component). Directional-hemispherical reflectance is the...

Photo-reflectance is an optical technique for investigating the material and electronic properties of thin films. Photo-reflectance measures the change...

surface reflectance anisotropy. For a given land area, the BRDF is established based on selected multiangular observations of surface reflectance. While...

In architecture, light reflectance value (LRV), is a measure of visible and usable light that is reflected from a surface when illuminated by a light...

various materials are determined to a large extent by their reflectance properties. Most reflectance models can be broadly classified into two categories: diffuse...

A reflecting telescope (also called a reflector) is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image...

The Photochemical Reflectance Index (PRI) is a reflectance measurement developed by John Gamon during his tenure as a postdoctorate fellow supervised by...

Bi-hemispherical reflectance is the reflectance of a surface under diffuse illumination (with no direct component). Bi-hemispherical reflectance is an important...

of log inverse reflectance (log 1/R) versus wavenumber. Alternative plots of Kubelka-Munk units can be used, which relate reflectance to concentration...

diffuse reflectance is firmly entrenched, as in diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and diffuse-reflectance ultraviolet–visible...

composed of polymers, cellulose and lignin. Vitrinite Reflectance (Ro%) : Vitrinite reflectance (Ro%) is a very important geochemical parameter used to...

the wavelength, cb is the body (diffuse) reflected component, cs is the surface (interface) (specular) reflected component, mb and ms are scale factors...

The Ames Reflectance Meter was developed in 1970 by Anton H. Clemens. It had a needle that indicated the intensity of blue light reflected from a paper...

absorbs strongly (less than 20 percent reflectance) from 5400 to 8000 nm. Although the high diffuse reflectance allows efficient laser pumping, the material...

Reflectance difference spectroscopy (RDS) is a spectroscopic technique which measures the difference in reflectance of two beams of light that are shone...

independent of the subject's reflectance, it is less likely to lead to incorrect exposures for subjects with unusual average reflectance. Taking an incident-light...

Reflectance paper is a surface that contains a lattice of mirrored dimples. The paper is printed with color and the angle-dependent reflectance function...

with an 18% reflectance across the visible spectrum, and a white reverse side with a 90% reflectance. Note that flat spectral reflectance is a stronger...

gemology, aventurescence (sometimes called aventurization) is an optical reflectance effect seen in certain gems. The effect amounts to a metallic glitter...

used for shape, texture, reflectance and motion capture often with structured light and a multi-camera setup. The reflectance field over a human face was...

Reflectativity is the second album by American jazz trumpeter Wadada Leo Smith and the debut with the ensemble New Dalta Ahkri, which was recorded live...

a reflecting cardinal is a cardinal number κ for which there is a normal ideal I on κ such that for every X∈I+, the set of α∈κ for which X reflects at...

Macrium Reflect is a disk imaging and backup utility for Microsoft Windows developed by Paramount Software UK Ltd in 2006. It is designed for both home...

The Reflecting Skin is a 1990 coming-of-age horror film written and directed by Philip Ridley and starring Jeremy Cooper, Viggo Mortensen, and Lindsay...
