Optical coherence tomography (OCT) has been applied in analyzing the micron-level structure of human tissue, including collagen fiber orientation mapping in the depth of human tissue, which is essential for understanding human uterus mechanics. Previous research, due to the imaging depth limitation of OCT, offers multiple fiber orientation information of separate layers of uterus sample, which could not provide the full-thickness information for analyzing the change of fiber orientation along the depth. To solve this problem, this research provides a method to combine the separate fiber orientation information and give an analysis based on the depth of fiber location.
