Abstract

We present a time domain and a frequency domain based algorithm for the analysis of spectroscopic terahertz data. The thickness information as well as the frequency dependent complex material parameters are extracted. Both methods can evaluate data obtained from measurements on sub-100μm thick samples, even in case of overlapping Fabry Perot echoes in the time domain. While the frequency domain approach provides highest accuracy, the time domain method is extremely computation efficient, enabling real time data extraction.
