(Term of radiometry/photometry/Radiance)
Reflectance is the ratio of incident luminous flux upon a surface which is reradiated in the visual spectrum.
Albedo is another Term for Reflectance.
Diffuse reflectance is the ratio of the flux reradiated by diffuse reflection (from a lambertian surface).
Unit of reflectance is percent (%) or a factor between 0 and 1.
