Lambertian reflectance — If a surface exhibits Lambertian reflectance, light falling on it is scattered such that the apparent brightness of the surface to an observer is the same regardless of the observer s angle of view. More technically, the surface luminance is… … Wikipedia
Bidirectional reflectance distribution function — The bidirectional reflectance distribution function (BRDF; {f r(omega i , omega o) }) is a 4 dimensional function that defines how light is reflected at an opaque surface. The function takes an incoming light direction, omega i , and outgoing… … Wikipedia

Leaf angle distribution — The Leaf Angle Distribution (or LAD) of a plant canopy refers to the mathematical description of the angular orientation of the leaves in the vegetation. Specifically, if each leaf is conceptually represented by a small flat plate, its… … Wikipedia
Light meter — A light meter is a device used to measure the amount of light. In photography, a light meter is often used to determine the proper exposure for a photograph. Typically a light meter will include a computer, either digital or analogue, which… … Wikipedia
Albedo — The albedo of an object is the extent to which it diffusely reflects light from the sun. It is therefore a more specific form of the term reflectivity. Albedo is defined asthe ratio of diffusely reflected to incident electromagnetic radiation. It … Wikipedia
Radiative transfer equation and diffusion theory for photon transport in biological tissue — Photon transport in biological tissue can be equivalently modeled numerically with Monte Carlo simulations or analytically by the radiative transfer equation (RTE). However, the RTE is difficult to solve without introducing approximations. A… … Wikipedia

Anti-reflective coating — Many coatings consist of transparent thin film structures with alternating layers of contrasting refractive index. Layer thicknesses are chosen to produce destructive interference in the beams reflected from the interfaces, and constructive… … Wikipedia
Normalized Difference Vegetation Index — Negative values of NDVI (values approaching 1) correspond to water. Values close to zero ( 0.1 to 0.1) generally correspond to barren areas of rock, sand, or snow. Lastly, low, positive values represent shrub and grassland (approximately 0.2 to 0 … Wikipedia
