The structures of fiber, including the distance between fibers and the arrangement direction of fibers, were quantitatively investigated using coherent terahertz (THz) wave. Composite fibers with periodically arranged 57% silk and 43% nylon are measured, then the specific absorption spectra due to intermolecular vibration and interference effect are observed in THz frequency region. It is shown that, not only the period and direction of woven but also the type of material could be specified by the THz spectroscopy. This study enlightens a novel method for fiber nondestructive inspection beyond microscopy imaging, which has potential to be applied in quality control, infrastructure disaster prevention.
