Abstract :
Continuous-wave (CW) and pulsed terahertz systems are used to take images of a ldquoTrdquo shape sample made of copper tape adhered on a polyethylene disc. Images are compared in terms of their resolution and contrast, and their dependencies on operation frequency, beam spot size, and scanning steps are discussed.
