Abstract :
We present a fiber-coupled cw THz system for fast and accurate imaging in the field of non-destructive testing. Fibercoupled THz antennas make this system flexible and robust. The time delay is not realized via an optical delay line but by moving the detector antenna along the optical axis (Z-Scan).
