In-line Medicine Inspection by Carbon Nanotube Terahertz Scanners

We report on a real-time one-dimensional medicine inspection with a carbon nanotube (CNT) terahertz (THz) scanner. On the basis of different THz transmittance of medicines, we demonstrated in-line identification of different types of medicine pills. The bendable feature of the CNT scanner is expected to lead to multi-view examinations in the future, enabling more accurate whole surface imaging.
