Abstract

Experimental results of terahertz 2-D synthetic aperture/ interferometric imaging are presented. The performance of an N element detector array is imitated by only one detector placed at N positions. The reconstructed images of small objects are in a good agreement with theoretical predictions. The imaging method can be used to detect objects behind a barrier and spectroscopically identify materials that exhibit a characteristic THz reflection spectra.
