multiangular การใช้
- Methods of immersion or multiangular ellipsometry are applied to find the optical constants of the material with rough sample surface or presence of inhomogeneous media.
- It is not until the mid-1990s, however, that a new generation of algorithms were proposed to estimate directly the biogeophysical variables of interest ( e . g ., the Fraction of Absorbed Photosynthetically Active Radiation or FAPAR ), taking advantage of the enhanced performance and characteristics of modern sensors ( in particular their multispectral and multiangular capabilities ) to take all the perturbing factors into account.
