We present for the first time a system and new algorithms for spectral THz-tomography. The electric field of single cycle ultra short THz-pulses can be measured time resolved in amplitude and phase. By focusing ultra short THz-pulses to a sample and

Different electro-optic crystals (CdTe, DAST, GaAs, GaP, and ZnTe) are investigated with respect to their ability as detection crystals for terahertz pulse electro-optic sampling at a wavelength of 1060 nm. Calculations of the detection response are

Imaging based on ultrashort terahertz (THz) pulses (100–3000 μm) is investigated. The measured pulses are analyzed and the resulting amplitude and time delay information are compared. An algorithm for discrimination of multiple pulses is presented

Die Presbyopie ist die bei weitem häufigste Fehlsichtigkeit, die bis heute keiner befriedigenden dauerhaften Korrektur zugänglich ist. Alle bisherigen Versuche, eine operative Therapie der Presbyopie zu entwickeln, haben bislang zu keiner klinisch

Electrooptical sampling of ultra-broadband terahertz (THz) radiation with the help of ultra-short 1060-nm pulses is reported for the first time. The THz pulses are generated by exciting a surface emitter (InAs) with a parabolic fiber laser amplifier
