Millimetre-wave- and terahertz sensors are a premier choice for the non-destructive inspection of letters and parcels as well as the control of products. A small versatile scanner ahs been developed, which allows to demonstrate this capability. The scanner employs mechanical scanning in transmission geometry, the transmitter ans receiver located at two rotating discs facing its other with the test sample linearly shifted in between. The paper describes the geometrical set-up and gives typical results.
