Abstract

We propose and demonstrate a scheme for two-dimensional terahertz reflection imaging using a time-domain phase-retrieval algorithm based on the dispersion relations of complex reflection coefficients. With this scheme, topographic images—as well as the dielectric functions of a structured sample—can be obtained. A composite sample made of a semiconductor and metals is characterized within depth and lateral errors of 50μm and 100μm.
