Abstract
Equations are presented for determining the optical properties of an absorbing uniaxial crystal by measuring the reflectance from a basal plane as a function of the angle of incidence and the angle of polarization. The technique is applied to a pyrolytic graphite crystal to determine the optical properties at 632.8 nm. The results are calculated numerically by use of a combination of the taylor-series and gradient methods. The best-fit values found for the optical constants of pyrolytic graphite at 632.8 nm are no=2.55, No=1.78, Ko=0.66, and ke=0.00
