Studying the pharmaceutical film coating process with terahertz sensing, optical coherence tomography and numerical modelling

摘要

Terahertz in-line sensing was successfully demonstrated on a production scale setting for measuring the coating thickness of individual pharmaceutical tablets during the film coating process. This paper reports on our recent research progress to combine terahertz in-line sensing, optical coherence tomography and numerical modelling in a lab scale setting to better understand the pharmaceutical film coating process.
