Reflectance anisotropy spectroscopy

Reflectance difference spectroscopy (RDS) is a spectroscopic technique which measures the difference in reflectance of two beams of light that are shone in normal incident on a surface with different linear polarizations. [1] It is also known as reflectance anisotropy spectroscopy (RAS). WebAnisotropic materials are those whose physical properties vary depending on their orientation. This is because the atomic densities in the crystal directions differ. The shear anisotropy factor calculates the degree of elastic anisotropy ( A ).
