Paper Abstract

The bireflectance effect is observed when a light beam is internally reflected in an anisotropic material. Generally, an unpolarized light beam splits into four beams on reflection. A new method for simultaneous measurement of the three refractive indices, in a single piece of a sample, via bireflectance, is demonstrated in the biaxial CdWO4 crystal. The three principal refractive indices of CdWO4 were obtained in the visible range. At λ = 633 nm, nX = 2.09±0.01, nY - nX = 0.052±0.001, and nZ - nX = 0.114±0.002.
