Abstract :
In this work we present a novel concept for fast and low-cost terahertz imaging. A fast and stable source for time delay is created by inserting a rotating piece of high-density polyethylene into the THz path of a terahertz time domain spectrometer [1]. We will present the specifications of a first implementation of this device as well as imaging examples.
