Web9. nov 2010 · The reflectance of a particular object or instance of material refers to the ratio of the total amount of light or electromagnetic radiation that is reflected from it’s surface compared to the total amount originally incident upon it. Reflectance is also sometimes referred to as a material’s reflection coefficient or reflection factor.As shown in Figure 1, a … Web6. dec 2016 · Reflectivity is the capacity of an object to reflect solar radiation. It is described as a function of radiation wavelength and is determined by the physical composition of … Web23. aug 2013 · Reflectance is the proportion of the radiation striking a surface to the radiation reflected off of it. Some materials can be identified by their reflectance spectra, so it is common to correct an image to reflectance as a first step toward locating or identifying features in an image.
