Abstract
We investigate dark-field imaging in the terahertz (THz) frequency regime w ith the intention to enhance image contrast through the analysis of scatter ing and diffraction signatures. A gold-on-TPX test structure and an archive d biomedical tissue sample are examined in conventional and dark-field tran smission geometry. In particular, the capability of the technique for tumor detection is addressed. (C) 2001 Optical Society of America.
