Abstract
Ultra wide-band frequency-modulated continuous-wave imaging systems operating in the lower terahertz regime have proven to be highly desirable for non-destructive testing applications. However, either quasi-optical configurations or the characteristics of typically used antennas as well as temperature-dependent nonlinear frequency sweeps restrict the achievable spatial resolution and reliability of these systems. In this contribution we report on the implementation of a dielectric rectangular rod antenna and a software-assisted feedback control loop to overcome these limitations.
