Abstract:   (1999 Views)
In this research, have been used THz Time Domain Spectroscopy(THz-TDS) at reflection mode contain two dipole GaAs photoconductive antenna in order to generation and detection THz waves and optical instruments such as silicon lens and parabolic mirror. generated Terahertz pulses have subpicosecond pulse duration  and spectral range of 0.1-2 THz. Absorption and refractive coefficients of histidine were calculated about 45.2 cm-1 and 1.57 respectively. Ability of concealed  samples detection is one of the advantages of this method.
Keywords: THz spectroscopy system, Reflection mode, Photoconductive antenna, Histidine.
