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

A surface which obeys Lambert's law is said to be Lambertian, and exhibits Lambertian reflectance. Such a surface has the same radiance/luminance when...

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

reflectance of any known material or coating over the ultraviolet, visible, and near-infrared regions of the spectrum. It exhibits highly Lambertian behavior...

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

the ratio of reflection of the diffuse term of incoming light (Lambertian reflectance), k a {\displaystyle k_{\text{a}}} , which is an ambient reflection...

and non-uniform lighting. Under Woodham's original assumptions — Lambertian reflectance, known point-like distant light sources, and uniform albedo — the...

non-Lambertian reflectance of the moon. The Oren–Nayar reflectance model, developed by Michael Oren and Shree K. Nayar in 1993, predicts reflectance from...

material. One common model for diffuse reflection is Lambertian reflectance, in which the light is reflected with equal luminance (in photometry) or radiance...

named because the reflected light from the Moon and Mars appear significantly brighter than predicted by simple Lambertian reflectance when at astronomical...
