C.M. Roland, in The Science and Technology of Rubber (Fourth Edition), 2013. 3.6.1 Orientation. Rubber elasticity arises from the orientation of chain segments, and the degree of this orientation underlies the mechanical properties. The most facile way to quantify the orientation is from the (optical) birefringence, defined as the difference in refractive indices for two perpendicular directions.
