Feurer1

The left image shows the four parabolic mirrors imaging the THz source (left) to the sample plane (right). The setup allows for a perfect diffraction limited imaging of the source to the sample plane. The image to the right shows the detector unit with the xyz translation stages and the optical delay line in the front.

 
 

Feurer2

The THz source is linearly polarized and illuminates an object at the sample plane. The detector then measures all three electric field components of the scattered (plus incident) field. Comparing these results to simulations allows for a fundamental understanding of the scattering properties of the sample in an octave spanning spectral region around 1 THz.
