This paper presents the experimental measurement of different materials when are irradiated by terahertz radiation (THz), applying THz spectroscopy techniques in the time domain. The radiation is emitted by a photoconductive antenna, excited by a femtosecond laser. The results are obtained when measuring the THz pulse transmitted through the materials when implementing a coherent and incoherent detection systems.Centro de Investigaciones ÓpticasFacultad de Ingenierí
