                        - 3D Orientation Imaging

Figure 2. Illustration of 3D orientation angle images of a high-density polyethylene (HDPE) film [7]. The color of a rod indicates the axial angle, |*q* |, and the symbol size represents the order parameter, <*P*2 >, as indicated. A higher <*P*2 > means a narrower distribution of the molecular orientation within the image pixel.
