Evaluation of crystal orientation focused especially on the c-axis and the degree of orientation is of great interest because the property of polymer film depends on stretching and thermal treatment in the production process. The beta scan in the transmission 2θ/θ arrangement is commonly used as a method to evaluate the orientation. Analysis using a whole pole figure which is obtained from reflection and transmission pole figure measurement allows you to understand orientation in more detail. Furthermore, it is possible to evaluate the orientation distribution quantitatively by using Herman’s orientation function which is calculated from the whole pole figure.
