| Abstract: | Reflectance Anisotropy spectroscopy (RAS) is a non-destructive optical probe of surfaces
that is capable of operating with in a wide range of environment. In this thesis,
by applying this optical technique attempt was made to determine the degree of
anisotropy of a biaxial Potassium Titanyl phosphate (KTP) crystal. Furthermore, by
using rotating polarizer-analyzer method, we have tried to develop a more accurate
and easy to use approach. The method used in this work can be used in situ real-time
measurements.The degree of Anisotropy is determined to be 7.4 × 10−3 ± .0001. |
