Abstract

Optical coherence tomography (OCT) features a contact-free nondestructive technique, offering high resolution images of internal
structures of materials. It represents an alternative process monitoring technology for coating processes, which does not depend on calibration models as are required for spectroscopic methods. Due to its high acquisition rate-OCT enables the measurement of local parameters of filmcoated pellets or tablets even for fast moving samples and therefore, features a perfect in-line process monitoring
technology.
