Abstract
A THz-system which can measure ultrashort THz-pulses simultaneously in transmission and in reflection under 0deg and off-axis under 15deg is presented. By combining the time resolved analysis of the three measurement directions, a high amount of information of the inner sample structure can be obtained. For first analysis concepts the main pulse amplitude and spectral information of transmittance measurements were evaluated.
