WebThe bidirectional reflectance distribution function (BRDF; (,) ) is a function of four real variables that defines how light is reflected at an opaque surface. It is employed in the … The reflectance of the surface of a material is its effectiveness in reflecting radiant energy. It is the fraction of incident electromagnetic power that is reflected at the boundary. Reflectance is a component of the response of the electronic structure of the material to the electromagnetic field of light, and is in … Zobraziť viac Hemispherical reflectance The hemispherical reflectance of a surface, denoted R, is defined as Spectral hemispherical reflectance The spectral hemispherical reflectance in frequency and … Zobraziť viac Reflection occurs when light moves from a medium with one index of refraction into a second medium with a different index of refraction. Specular reflection from a body of water is calculated by the Fresnel equations. Fresnel reflection … Zobraziť viac • Bidirectional reflectance distribution function • Colorimetry • Emissivity • Lambert's cosine law • Transmittance Zobraziť viac For homogeneous and semi-infinite (see halfspace) materials, reflectivity is the same as reflectance. Reflectivity is the square of the magnitude of the Fresnel reflection coefficient, which is the ratio of the reflected to incident electric field; as such the … Zobraziť viac Given that reflectance is a directional property, most surfaces can be divided into those that give specular reflection and those that give Zobraziť viac The generalization of reflectance to a diffraction grating, which disperses light by wavelength, is called diffraction efficiency.

Reflection of light is either specular (mirror-like) or diffuse (retaining the energy, but losing the image) depending on the nature of the interface. In specular reflection the phase of the reflected waves depends on the choice of the origin of coordinates, but the relative phase between s and p (TE and TM) polarizations is fixed by the properties of the media and of the interface between them. WebReflection (%Reflectance, etc.) is an interface, or surface phenomenon. While Transmittance (%Transmittance, etc.) is a bulk phenomenon. For example, anti-reflection coatings are often applied to...
