Abstract-Cost-efficient delay generator for fast terahertz imaging
Optics Letters, Vol. 39, Issue 16, pp. 4863-4866 (2014)
We present a fast and low-cost delay generator for terahertz (THz) waves that transfers a rotational motion of a transparent dielectric cube into an effective THz delay. The device is easily implemented in the THz beam path and allows for coherent sampling over 40 ps with a scan rate of hundreds of hertz. Furthermore, we show that our approach is particularly suitable for fast THz imaging.
