= Directional-hemispherical reflectance
{wiki=Directional-hemispherical_reflectance}
Directional-hemispherical reflectance (DHR) refers to a measurement of reflectance that characterizes how a surface reflects incoming light in a specific directional manner across a hemispherical angle. It is particularly important in fields like optics, materials science, and remote sensing because it provides insights into the reflective properties of materials when they are lit by a light source from a particular direction.
