Terahertz reflectometry: a model system for the inverse problem

Summary form only given. We have performed preliminary reflectance measurements for the purposes of demonstrating the homology between THz reflectometry and acoustic seismography. These measurements have been performed using a newly developed THz system, in which the femtosecond pulse train is delivered to both the transmitter and receiver via single-mode optical fiber. This is an important advantage, since one can move the THz receiver antenna across the table without changing the alignment of the optical gating beam. As a result, one may easily measure the reflected THz field at many different receiver positions
